DESCRIPTION OF BUSINESS	3 Months Ended
	Mar. 31, 2015
DESCRIPTION OF BUSINESS [Abstract]
DESCRIPTION OF BUSINESS	1	DESCRIPTION OF BUSINESS
	Procera Networks, Inc., a Delaware corporation (“Procera” or the “Company”), is a leading provider of Subscriber Experience Assurance (“SEA”) solutions, based on Deep Packet Inspection technology, that enable mobile and broadband network operators and enterprises managing private networks, including higher education institutions, businesses and government entities (collectively referred to as network operators), to gain enhanced visibility into, and control of, their networks and to create and deploy new services for their end user subscribers.  The Company sells its products through its direct sales force, resellers, distributors, systems integrators and other equipment manufacturers in the Americas, Asia Pacific and Europe.
	Procera was incorporated in 2001 and its common stock currently trades on the NASDAQ Global Select Market under the trading symbol “PKT”. The Company reincorporated from the state of Nevada to the state of Delaware in June 2013.
	Merger Agreement with Francisco Partners
	On April 21, 2015, Procera entered into an Agreement and Plan of Merger (the “Merger Agreement”) with KDR Holding, Inc., a Delaware corporation (“Parent”), and KDR Acquisition, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Purchaser”). Parent and Purchaser are beneficially owned by affiliates of Francisco Partners IV, L.P. and Francisco Partners IV-A, L.P. (collectively, “Francisco Partners”).
	Pursuant to the terms of the Merger Agreement, Purchaser will commence a tender offer (the “Offer”) to purchase all of the outstanding shares of common stock, par value $0.001 per share, of Procera (the “Shares”), at a price of $11.50 per Share, net to the seller thereof in cash, without interest (such amount, as it may be adjusted on the terms set forth in the Merger Agreement, the “Offer Price”), and subject to deduction for any required withholding of taxes. Pursuant to the terms of the Merger Agreement, Purchaser is obligated to commence the Offer as promptly as practicable, but in no event later than May 5, 2015. The board of directors of Procera (the “Board”) has unanimously adopted the Merger Agreement.
	The consummation of the Offer is subject to customary closing conditions, including, among other things: (i) the expiration or termination of the waiting period under any applicable antitrust laws; (ii) there having been validly tendered and not validly withdrawn prior to the expiration of the Offer that number of Shares representing one Share more than 50% of the total number of Shares then-outstanding on a fully diluted basis; (iii) the absence of a material adverse effect with respect to Procera; and (iv) other customary conditions to the Offer set forth in Annex A to the Merger Agreement. The consummation of the Offer is not subject to any financing condition.
	Following the consummation of the Offer, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Purchaser will be merged with and into Procera, with Procera continuing as the surviving corporation and a wholly owned subsidiary of Parent (the “Merger”). The Merger Agreement provides that the Merger will be effected pursuant to Section 251(h) of the General Corporation Law of the State of Delaware, without a vote of the stockholders of Procera.
	At the effective time of the Merger (the “Effective Time”), each Share that is outstanding immediately prior to the Effective Time, other than the Shares owned by Procera, Parent or Purchaser, or by stockholders who have validly exercised and perfected their appraisal rights under Delaware law, will be canceled and converted into the right to receive the Offer Price, payable to the holder thereof on the terms and subject to the conditions set forth in the Merger Agreement.
	In addition, at the Effective Time, (i) each option to purchase Shares, to the extent vested as of the Effective Time (each, a “Vested Company Option”), will be canceled and converted into the right to receive an amount in cash equal to the product of (a) the excess, if any, of the Offer Price over the exercise price of such Vested Company Option and (b) the number of Shares that may be acquired upon exercise of such Vested Company Option, without interest and subject to deduction for any required withholding of taxes, and (ii) each restricted stock unit award, to the extent vested as of the Effective Time (but for which Shares have not yet been issued) (each, a “Vested Company RSU”), and each restricted stock award that remains subject to vesting conditions (each, an “Unvested Company RSA”), will be canceled and converted into the right to receive an amount in cash equal to the product of (y) the excess, if any, of the Offer Price over the purchase price payable for such Vested Company RSU or Unvested Company RSA, if any, and (z) the number of Shares subject to (or deliverable under) such Vested Company RSU or Unvested Company RSA, in each case without interest and subject to deduction for any required withholding of taxes. At the Effective Time, each option to purchase Shares that is unvested as of the Effective Time, each restricted stock unit award that is unvested as of the Effective Time, and each option to purchase Shares with an exercise price at or above of the Offer Price, will be canceled for no consideration.
	Procera, Parent and Purchaser have made customary representations, warranties and covenants in the Merger Agreement. Procera’s covenants include, among other things, covenants regarding the operation of Procera’s business prior to the Effective Time and covenants not to solicit third party proposals relating to alternative transactions or provide information or enter into discussions in connection with alternative transactions, subject to exceptions to permit the Board to comply with its fiduciary duties
	The Merger Agreement also includes customary termination rights in favor of each of Procera and Parent, including, among others, if the transactions contemplated by the Merger Agreement are not consummated on or before August 30, 2015 or if Procera terminates the Merger Agreement in compliance with its terms in order to accept a superior proposal. Upon termination of the Merger Agreement under certain circumstances, Procera has agreed to pay Parent a termination fee of approximately $7.2 million.
	The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is filed as Exhibit 2.1 to this Quarterly Report on Form 10-Q and incorporated herein by reference.
	If Procera consummates the Merger, Procera will become a wholly-owned subsidiary of Parent. Accordingly, the remainder of this Quarterly Report on Form 10-Q, which assumes Procera remains a standalone business, should be read with the understanding that should the Merger be completed, Parent will have the power to control the conduct of Procera’s business.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Basis of Presentation
	Procera has prepared the condensed consolidated financial statements included herein pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim financial information.  Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations.  However, in the opinion of management, the financial statements include all the normal and recurring adjustments that are necessary to fairly present the results of the interim periods presented. The interim results presented are not necessarily indicative of results for any subsequent interim period, the year ending December 31, 2015 or any other future period. The consolidated balance sheet at December 31, 2014 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.  These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in Procera’s Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 13, 2015.
	The condensed consolidated financial statements present the accounts of Procera and its wholly-owned subsidiaries.  All significant inter-company balances and transactions have been eliminated.
	Significant Accounting Policies
	The accounting and reporting policies of the Company conform to GAAP.  There have been no significant changes in the Company’s significant accounting policies during the three months ended March 31, 2015 compared to what was previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 13, 2015.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers”, issued as a new Topic, Accounting Standards Codification (“ASC”) Topic 606.  The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized.  The core principle of the guidance is that a company should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  This ASU will be effective for fiscal 2018, including interim periods within that reporting period and can be adopted by the Company either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the effect that adopting this new accounting guidance will have on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (ASU 2014-12).  The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition.  A reporting entity should apply the existing guidance in ASC Topic No. 718, “Compensation – Stock Compensation”, as it relates to awards with performance conditions that affect vesting to account for such awards.  The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015.  Early adoption is permitted.  Entities may apply the amendments in ASU 2014-12 either: (1) prospectively to all awards granted or modified after the effective date; or (2) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter.  The adoption of ASU 2014-12 is not expected to have a material effect on the Company’s consolidated financial statements or disclosures.
	In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements”, which provides new guidance related to the disclosures around going concern.  The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted.  The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.

	As of March 31, 2015 and December 31, 2014, all investments were classified as available-for-sale with unrealized gains and losses recorded as a separate component of accumulated other comprehensive income (loss).  Cash equivalents consist of highly liquid investments with remaining maturities of three months or less at the date of purchase.  Short-term investments have a remaining maturity of greater than three months at the date of purchase and an effective maturity of up to 24 months.  The weighted average maturity of the portfolio does not exceed 12 months.  As of March 31, 2015 and December 31, 2014, the Company had certain investments with a maturity greater than one year.  As of March 31, 2015 and December 31, 2014, the Company had $10.7 million and $12.8 million, respectively, in investments with a maturity of greater than one year.  However, management has the ability, if necessary, to liquidate any of its investments in order to meet the Company’s liquidity needs in the next 12 months.  Accordingly, investments with contractual maturities greater than one year from the date of purchase are classified as short-term on the accompanying condensed consolidated balance sheets.  None of the Company’s short-term investments have been at a continuous unrealized loss position for greater than 12 months.
	The Company reviews its investments for impairment quarterly.  For investments with an unrealized loss, the factors considered in the review include the credit quality of the issuer, the duration that the fair value has been less than the adjusted cost basis, severity of impairment, reason for the decline in value and potential recovery period, the financial condition and near-term prospects of the investees, and whether the Company would be required to sell an investment due to liquidity or contractual reasons before its anticipated recovery.  Based on its review, the Company did not identify any investments that were other-than-temporarily impaired during the three months ended March 31, 2015 and 2014.
	The Company did not incur any material realized gains or losses in either of the three months ended March 31, 2015 or 2014.  The cost of securities sold was determined based on the specific identification method.

FAIR_VALUE_MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended

FAIR VALUE MEASUREMENTS [Abstract]
FAIR VALUE MEASUREMENTS	4	FAIR VALUE MEASUREMENTS
	Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  When determining fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability.
	The three levels of inputs that may be used to measure fair value are as follows:
		Level 1-	Quoted prices in active markets for identical assets or liabilities.
		Level 2-	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets with insufficient volume or infrequent transactions (less active markets), or model-derived valuations in which all significant inputs are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities.
		Level 3-	Unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of assets or liabilities.
	The following is a summary of cash equivalents and short-term investments by type of instrument as of March 31, 2015 and December 31, 2014, measured at fair value on a recurring basis (in thousands):
			31-Mar-15

	Money market funds		$	62	$	—	$	—	$	62

	Money market funds		$	109	$	—	$	—	$	109

	Treasury and agency notes and bills			—		54,442		—		54,442
	Corporate bonds			—		25,404		—		25,404
	Total assets measured at fair value		$	109	$	90,642	$	—	$	90,751
	In general, and where applicable, the Company uses quoted market prices in active markets for identical assets to determine fair value.  This pricing methodology applies to Level 1 investments which are comprised of money market funds.  If quoted prices in active markets for identical assets are not available, then the Company uses quoted prices for similar assets or inputs other than quoted prices that are observable, either directly or indirectly.  These investments are included in Level 2 and consist of commercial paper, U.S. agency securities and U.S. Government and corporate bonds. U.S. agency securities and U.S. Government and corporate bonds are valued at a consensus price, which is a weighted average price based on market prices from a variety of industry standard data providers used as inputs to a distribution-curve based algorithm. Commercial paper is valued using market prices where available, adjusting for accretion of the purchase price to face value at maturity.
	The Company did not have any transfers between Level 1 and Level 2 fair value instruments in either of the three months ended March 31, 2015 or 2014.

	Inventories
	Inventories are stated at the lower of cost (on a specific identification or weighted average cost basis), or market. Inventories at March 31, 2015 and December 31, 2014 consisted of the following (in thousands):
			March 31,			December 31,
			2015			2014
	Finished goods		$	14,682		$	14,638
	Raw materials			267			199
	Inventories, net		$	14,949		$	14,837
	Inventories also include demonstration units located at various customer locations and customer service inventories.  The demonstration units and customer service inventories are stated at lower of cost (on a specific identification or weighted average cost basis) or market.  The Company provides demonstration units to customers who evaluate the Company's products, and upon a successful trial, may purchase such products.  The Company carries customer service inventories because it generally provides product warranties for 12 months and earns revenue by providing enhanced and extended support contracts during and beyond this warranty period.  Customer service inventories are provided for customer use permanently or on a temporary basis while the defective unit is being repaired.  The Company reduces the carrying value of demonstration units and customer service inventories for differences between cost and estimated net realizable value, taking into consideration expected demand, technological obsolescence, the physical condition of the unit and other information.  If actual results vary significantly from expectations, additional write-downs may be required, resulting in additional charges to operations.

	Warranty Reserve
	The Company warrants its products against material defects for a specific period of time, generally 12 months. The Company provides for the estimated future costs of warranty obligations in cost of sales when the related revenue is recognized. The accrued warranty costs represent the best estimate at the time of sale of the total costs that the Company expects to incur to repair or replace product parts which fail while still under warranty.  The amount of accrued estimated warranty costs is primarily based on current information on repair costs.  The Company periodically reviews the accrued balances and updates the historical warranty cost trends.

	Common Stock Transactions
	On January 9, 2013, pursuant to the Company’s acquisition of Vineyard, the Company issued 825,000 unregistered shares of its common stock with a value of approximately $14.3 million as part of the purchase consideration in exchange for 100% of the outstanding securities of Vineyard and deferred compensation to the founders of Vineyard. On February 13, 2013, the Company filed with the SEC a Registration Statement on Form S-3 covering the resale of these shares. The Registration Statement on Form S-3 was declared effective by the SEC on March 7, 2013.  Pursuant to the Vineyard acquisition agreement, 518,000 shares were transferred to the former Vineyard shareholders at closing, with the remainder being held in escrow for a period of 12, 18 or 36 months from the closing of the acquisition.  In January 2014, 178,000 shares were released from the escrow related to the retention agreements with Vineyard’s three founders after one year of continuous employment with the Company.  In July 2014, 124,000 shares were released from escrow related to the resolution of certain contingencies. As of March 31, 2015, 5,000 shares remain in escrow.
	Stock Incentive Plans
	The Company’s 2007 Equity Incentive Plan, as amended (the “Plan”), provides for the grant of stock options, restricted stock awards and restricted stock unit awards to eligible employees, consultants and non-employee directors of the Company.  As of March 31, 2015, 224,000 shares of the Company’s common stock were available for future grant under the Plan.

NET INCOME (LOSS) PER SHARE [Abstract]
NET INCOME (LOSS) PER SHARE	8	NET INCOME (LOSS) PER SHARE
	Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that could occur from common shares issuable upon the exercise of outstanding stock options or warrants and the vesting of restricted stock awards and restricted stock units, which are reflected in diluted earnings per share by application of the treasury stock method.  Under the treasury stock method, the amount that the employee must pay for exercising stock options or warrants, the amount of stock-based compensation cost for future services that the Company has not yet recognized, and the amount of tax benefit that would be recorded in additional paid-in capital upon exercise of options and warrants are assumed to be used to repurchase shares.
	The following table sets forth the computation of basic and diluted net loss per share and potential shares of common stock that are not included in the diluted net loss per share calculation because their effect is anti-dilutive (in thousands, except per share data):

	Total stock-based compensation expense		$	1,207		$	1,313
	No income tax benefits were recognized in either of the three months ended March 31, 2015 or 2014 due to operating losses.  No stock-based compensation has been capitalized in inventory due to the immateriality of such amounts.
	As of March 31, 2015, total unrecognized compensation cost related to unvested stock options was $5.0 million, net of estimated forfeitures, which is expected to be recognized over an estimated weighted average period of 2.30 years, and total unrecognized compensation cost related to unvested restricted stock awards and restricted stock units was $4.4 million, net of estimated forfeitures, which is expected to be recognized over an estimated weighted average period of 2.65 years.
	The fair value of each option grant is estimated on the date of grant using the Black-Scholes option valuation model.  The fair value of each restricted stock award and restricted stock unit is calculated based upon the closing stock price of the Company’s common stock on the date of the grant.  The expense for stock-based awards is recognized over the requisite service period using the straight-line attribution approach.
	The following assumptions were used in determining the fair value of stock options granted during the three months ended March 31, 2015 and 2014:
			Three Months Ended
			March 31,
			2015			2014
	Expected term (years)			5.27			4.91
	Expected volatility			62.1	%		70.42	%
	Risk-free interest rate			1.44	%		1.56	%
	Expected dividend yield			0	%		0	%
	The weighted average grant date fair value of options granted during the three months ended March 31, 2015 and 2014 was $4.99 and $7.09, respectively.
	The Company calculated the expected term of stock options granted using historical exercise data.  The Company used the number of days between the grant and the exercise dates to calculate a weighted average of the holding periods for all awards (i.e., the average interval between the grant and exercise or post-vesting cancellation dates), adjusted as appropriate.  Expected volatilities were estimated using the historical share price performance over a period equivalent to the expected term of the option.  The risk-free interest rate for a period equivalent to the expected term of the option was extrapolated from the U.S. Treasury yield curve in effect at the time of the grant.  The Company has never paid cash dividends and does not anticipate paying cash dividends in the foreseeable future.

	Legal
	The Company is periodically involved in legal actions and claims that arise as a result of events that occur in the normal course of operations.  Except as set forth under the caption “Litigation Relating to the Company’s Pending Merger with Francisco Partners” below, the Company does not believe that any of its legal actions and claims will have, individually or in the aggregate, a material adverse effect on the Company’s financial position or results of operations.
	Litigation Relating to the Company’s Pending Merger with Francisco Partners
	Following the announcement that the Company had entered into the Merger Agreement with Parent and Purchaser on April 21, 2015, eight putative stockholder class action complaints challenging the Offer, the Merger and the transactions contemplated thereby were filed on behalf of purported Company stockholders in the Court of Chancery of the State of Delaware. These complaints were: (1) Sverdlov v. Procera Networks, Inc., et al., Case No.10951, filed on April 28, 2015, (2) Feniello v. Brear, et al., Case No. 10952, filed on April 28, 2015, (3) Lemmon v. Brear, et al., Case No. 10961, filed on April 29, 2015, (4) Clark v. Procera Networks, Inc., et al., Case No. 10968, filed on April 29, 2015, (5) Torpey v. Procera Networks, Inc., et al., Case No. 10969, filed on April 29, 2015, (6) Schiller v. Procera Networks, Inc., et al., Case No. 10971, filed on April 30, 2015, (7) Rosenfield v. Procera Networks, Inc. et al., Case No 10973 filed on April 30, 2015, and (8) Stupar v. Procera Networks, Inc., et al., Case No. 10975, filed on May 1, 2015 (collectively, the "Complaints").
	The Sverdlov, Torpey, Schiller and Rosenfeld complaints name the Company, the members of the Board, Francisco Partners, Parent and Purchaser as defendants. The Clark and Stupar complaints name the Company, the members of the Board, Parent and Purchaser as defendants. The Feniello complaint names the members of the Board, Francisco Partners, Parent and Purchaser as defendants. The Lemmon complaint names the members of the Board, Francisco Partners, Francisco Partners Management, L.P., Parent and Purchaser as defendants.
	In general, the Complaints allege that the members of the Board breached their fiduciary duties to the Company's stockholders by taking one or more of the following actions: (i) agreeing to an unfair and inadequate Offer Price for the Shares, (ii) accepting unreasonable deal protection measures in the Merger Agreement that dissuades other potential bidders from making competing offers, (iii) failing to properly value the Company and take steps to maximize the value of the Company, (iv) engaging in self-dealing, and (v) ignoring the conflicts of interest present in the Company's financial advisor.
	The Complaints also allege that one or more of the following defendants: the Company, Francisco Partners, Francisco Partners Management, L.P., Parent and Purchaser aided and abetted the members of the Board in breaching their fiduciary duties to the Company's stockholders.
	In each Complaint, the plaintiffs have requested certification as a class, injunctive relief, monetary damages, an award of attorneys' fees, other costs and fees and other equitable relief that the court may deem just and proper. The Feniello, Lemmon, Clark, Schiller and Rosenfeld complaints have also requested that the court rescind and set aside the transactions in the event that the Offer and the Merger are consummated.
	These lawsuits are in their early stages and it is not possible to determine the potential outcome of any of these lawsuits or to make any estimate of probable losses at this time. Each of the Company, the Board, Francisco Partners, Francisco Partners Management, L.P., Parent and Purchaser believes that these lawsuits are completely without merit and each intends to vigorously defend against all allegations that have been asserted.
	Operating Leases
	The Company leases its operating and office facilities for various terms under long-term, non-cancelable operating lease agreements.  The leases expire at various dates through 2024.  In the normal course of business, it is expected that these leases will be renewed or replaced by leases on other properties.  The leases provide for increases in future minimum annual rental payments based on defined increases which are generally meant to correlate with the Consumer Price Index, subject to certain minimum increases.  Also, the agreements generally require the Company to pay executory costs (real estate taxes, insurance and repairs).
	As of March 31, 2015, future minimum lease payments due under operating leases are as follows (in thousands):
	Fiscal years ending December 31,		Amount
	2015 (remaining nine months)		$	794
	2016			919
	2017			704
	2018			476
	2019			281
	Thereafter			1,041
	Total minimum lease payments		$	4,215
	Purchase Commitments
	The Company issues purchase orders to third-party suppliers that may not be cancelable.  As of March 31, 2015, the Company had open non-cancelable purchase orders amounting to approximately $11.4 million, primarily with the Company’s third-party suppliers.
	Concentrations
	For the three months ended March 31, 2015, revenue from Itochu Techno-Solutions Corp. represented 14% of net revenue, British Telecommunications plc represented 13% of net revenue, and revenue from Shaw Communications, Inc. and one other customer each represented 11% of net revenue with no other single customer accounting for more than 10% of net revenue.  For the three months ended March 31, 2014, no customer accounted for more than 10% of net revenue.
	At March 31, 2015, accounts receivable from two customers represented 30% and 10%, respectively, of total accounts receivable, with no other single customer accounting for more than 10% of the accounts receivable balance.  At December 31, 2014, accounts receivable from one customer represented 13% of total accounts receivable with no other single customer accounting for more than 10% of the accounts receivable balance.  As of March 31, 2015 and December 31, 2014, approximately 92% and 93%, respectively, of the Company’s total accounts receivable were due from customers outside the United States.
	Indemnification
	The Company generally agrees to indemnify customers against legal claims that the Company’s products infringe certain third party property rights. As of March 31, 2015 and 2014, the Company has not been required to make any payments resulting from infringement claims asserted against customers and has not recorded any related reserves.

INCOME TAXES [Abstract]
INCOME TAXES	11	INCOME TAXES
	The Company’s effective tax rate was approximately zero percent for the three months ended March 31, 2015 and 2% for the three months ended March 31, 2014.  For the three months ended March 31, 2015, the Company recorded an income tax expense of $11,000 on a loss before provision for income taxes of $3.3 million.  For the three months ended March 31, 2014, the Company recorded an income tax benefit of $0.1 million on a loss before provision for income taxes of $6.1 million. The effective tax rate for each of the three months ended March 31, 2015 and 2014 differs from the federal statutory tax rate as a result of the income tax expense related to the amortization of the indefinite life intangibles, state taxes and earnings taxed in foreign jurisdictions and unbenefited losses due to full valuation allowances in the U.S., Canada and Sweden.
	In 2002, the Company established a valuation allowance for substantially all of its deferred tax assets. Since that time, the Company has continued to record a valuation allowance.  A valuation allowance is required to be established or maintained when it is more likely than not that all or a portion of deferred tax assets will not be realized.  The Company will continue to reserve for substantially all net deferred tax assets until there is sufficient evidence to warrant reversal.
	The Company recognizes interest and penalties related to uncertain tax positions in income tax expense.  As of March 31, 2015, the Company had no accrued interest or penalties related to uncertain tax positions.   The federal returns for the years ended 2011 through the current period and most state returns for the years ended 2010 through the current period remain open to examination.  In addition, all of the net operating losses and research and development credit carryforwards that may be used in future years are still subject to adjustment.  The Company is also subject to examinations in Australia, Canada, Japan, Singapore and Sweden beginning in 2007 through the current period.
	At March 31, 2015, the Company had $196,000 of unrecognized tax benefits, none of which would affect the Company’s effective tax rate if recognized.  The Company currently has a full valuation allowance against its U.S. net deferred tax assets which would impact the timing of the effective tax rate benefit should any of these uncertain tax positions be favorably settled in the future.  The Company does not anticipate that the total unrecognized tax benefits will change significantly over the next twelve months.

	The Company has one reportable operating segment representing the PacketLogic business. The Company’s Chief Operating Decision Maker (“CODM”) evaluates the performance of segments and makes decisions regarding allocation of resources based on certain metrics including segment revenue, gross profit and operating income (loss) measures before other income (expense), net and income taxes. Certain operating expenses, including stock-based compensation expenses; business development expenses; cost reduction efforts; acquisition-related intangible asset and impairment charges, and deferred compensation amortization are not allocated to segments.  The CODM does not review asset information by segment.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Basis of Presentation	Basis of Presentation
	Procera has prepared the condensed consolidated financial statements included herein pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim financial information.  Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules and regulations.  However, in the opinion of management, the financial statements include all the normal and recurring adjustments that are necessary to fairly present the results of the interim periods presented. The interim results presented are not necessarily indicative of results for any subsequent interim period, the year ending December 31, 2015 or any other future period. The consolidated balance sheet at December 31, 2014 has been derived from the audited consolidated financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements.  These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in Procera’s Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 13, 2015.
	The condensed consolidated financial statements present the accounts of Procera and its wholly-owned subsidiaries.  All significant inter-company balances and transactions have been eliminated.
Significant Accounting Policies	Significant Accounting Policies
	The accounting and reporting policies of the Company conform to GAAP.  There have been no significant changes in the Company’s significant accounting policies during the three months ended March 31, 2015 compared to what was previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 13, 2015.
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers”, issued as a new Topic, Accounting Standards Codification (“ASC”) Topic 606.  The new revenue recognition standard provides a five-step analysis of transactions to determine when and how revenue is recognized.  The core principle of the guidance is that a company should recognize revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  This ASU will be effective for fiscal 2018, including interim periods within that reporting period and can be adopted by the Company either retrospectively or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the effect that adopting this new accounting guidance will have on its consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (ASU 2014-12).  The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition.  A reporting entity should apply the existing guidance in ASC Topic No. 718, “Compensation – Stock Compensation”, as it relates to awards with performance conditions that affect vesting to account for such awards.  The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015.  Early adoption is permitted.  Entities may apply the amendments in ASU 2014-12 either: (1) prospectively to all awards granted or modified after the effective date; or (2) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter.  The adoption of ASU 2014-12 is not expected to have a material effect on the Company’s consolidated financial statements or disclosures.
	In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements”, which provides new guidance related to the disclosures around going concern.  The new standard provides guidance around management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted.  The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.
