Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Basis of Presentation | 1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Silver Spring Networks, Inc. (the “Company”, “we”, “us” and “our”) have been prepared in accordance with generally accepted accounting principles in the United States, or U.S. GAAP, for interim financial information as well as the instructions to Form 10-Q and applicable rules and regulations of the U.S. Securities and Exchange Commission, or SEC. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, including normal recurring accruals, considered necessary for a fair presentation have been included. The results of operations for the three and nine months ended September 30, 2016, are not necessarily indicative of the results that may be expected for the year ending December 31, 2016, or any future period. The information included in this Quarterly Report on Form 10-Q should be read in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” “Risk Factors,” “Quantitative and Qualitative Disclosures About Market Risk,” and the Consolidated Financial Statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015. The preparation of unaudited condensed consolidated financial statements necessarily requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the condensed consolidated balance sheet dates and the reported amounts of revenues and expenses for the periods presented. Actual results could differ materially from those estimates under different assumptions or conditions. As a result, the quarterly results may not be indicative of the full year results. The condensed consolidated financial statements include the accounts of Silver Spring Networks, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated. |

Earnings Per Share [Abstract] | |
Net (Loss) Income Per Share | 3. Net (loss) income per share Basic net (loss) income per share is computed by dividing the net (loss) income by the weighted-average number of shares of common stock outstanding during the period. Diluted net (loss) income per share is computed by dividing the net (loss) income by the weighted-average number of shares of common stock outstanding plus dilutive potential shares of common stock outstanding during the period. Dilutive consist of common shares issuable upon issuances of shares pursuant to the 2012 Employee Stock Purchase Plan, or ESPP, vesting of and contingently issuable We include the common shares underlying PSUs in the calculation of diluted net income per share when they become contingently issuable and exclude such shares when they are not contingently issuable. Certain potential shares of common stock were excluded from the computation of diluted net income per share because their effect would be anti-dilutive The following table sets forth the computation of basic and diluted net (loss) income per share (in thousands, except per share data): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Net (loss) income $ (15,249 ) $ (622 ) $ (7,642 ) $ 18,108 Net (loss) income per share Basic $ (0.29 ) $ (0.01 ) $ (0.15 ) $ 0.36 Diluted $ (0.29 ) $ (0.01 ) $ (0.15 ) $ 0.35 Weighted average shares used to compute net (loss) income per share Basic 51,743 50,188 51,244 49,789 Dilutive effect of employee equity incentive plans — — — 1,468 Diluted 51,743 50,188 51,244 51,257 The following potential common shares outstanding were excluded from the computation of diluted net (loss) income per share because including them would have been anti-dilutive (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Employee equity awards 7,957 7,291 7,957 3,873 |

We periodically review our marketable debt securities for other-than-temporary impairment. We consider factors such as the duration, severity and the reason for the decline in value, the potential recovery period and our intent to sell. We also consider whether it is more likely than not that we will be required to (i) sell the debt securities before recovery of their amortized cost basis, and (ii) the amortized cost basis cannot be recovered as a result of credit losses. As of September 30, 2016, we anticipate that we will recover the entire amortized cost basis of such available-for-sale debt securities and have determined that no other-than-temporary impairments associated with credit losses were required to be recognized during the three and nine months ended September 30, 2016 and 2015. It is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases. There were insignificant gross realized gains or losses from available-for-sale securities during the three and nine months ended September 30, 2016 and 2015. |
Fair Value Measurements
Fair Value Measurements | 9 Months Ended |
Sep. 30, 2016 | |
Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 5. Fair Value Measurements We determine the fair values of our financial instruments based on a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The classification of a financial asset or liability within the hierarchy is based upon the lowest level input that is significant to the fair value measurement. Under ASC Topic 820, Fair Value Measurement and Disclosures Level 1—Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2—Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3—Unobservable inputs in which there is little or no market data, which requires us to develop our own assumptions. Level 1 measurements are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 measurements are obtained from readily available pricing sources for comparable instruments, identical instruments in less active markets, or models using market observable inputs. We did not have any transfers of financial instruments between valuation levels during the nine months ended September 30, 2016 and year ended December 31, 2015. Assets Measured at Fair Value on a Recurring Basis As of September 30, 2016, financial assets recorded at fair value on a recurring basis were determined using the following inputs (in thousands): Fair Value Measurement Using Quoted Prices in Significant Active Markets for Other Significant Identical Observable Unobservable Instruments Inputs Inputs (Level 1) (Level 2) (Level 3) Total Cash equivalents: Money-market funds $ 3,430 $ — $ — $ 3,430 Total cash equivalents 3,430 — — 3,430 Short-term investments: U.S. Government and agency obligations — 37,698 — 37,698 U.S. and foreign corporate debt securities — 27,612 — 27,612 Total short-term investments — 65,310 — 65,310 Total assets measured at fair value $ 3,430 $ 65,310 $ — $ 68,740 As of December 31, 2015, financial assets recorded at fair value on a recurring basis were determined using the following inputs (in thousands): Fair Value Measurement Using Quoted Prices in Significant Active Markets for Other Significant Identical Observable Unobservable Instruments Inputs Inputs (Level 1) (Level 2) (Level 3) Total Cash equivalents: Money-market funds $ 6,001 $ — $ — $ 6,001 Total cash equivalents 6,001 — — 6,001 Short-term investments: U.S. Government and agency obligations — 38,290 — 38,290 U.S. and foreign corporate debt securities — 18,895 — 18,895 Foreign governments and multi-national agency obligations — 1,996 — 1,996 Total short-term investments — 59,181 — 59,181 Total assets measured at fair value $ 6,001 $ 59,181 $ — $ 65,182 As of September 30, 2016 and December 31, 2015, there were no liabilities that are measured and recorded at fair value on a recurring basis. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis As of September 30, 2016, we had no liabilities measured at fair value on a nonrecurring basis. Our intangible assets are measured at fair value on a nonrecurring basis, if impairment is indicated. During the three and nine months ended September 30, 2016, intangible assets were measured at fair value resulting in an impairment charge of $2.2 million, which was recorded in the condensed consolidated statements of operations. We measured the fair value of the assets primarily using discounted cash flow projections. The discounted cash flow projections require estimates for expected performance such as revenue, gross margin and operating expenses, in order to discount the sum of future independent cash flows using discount rates. Acquired intangible assets are classified as Level 3 assets, due to the absence of quoted market prices. See Note 7, Goodwill and Intangibles Assets , for further information. As of December 31, 2015, there were no assets and liabilities that are measured and recorded at fair value on a nonrecurring basis except for assets and liabilities valued on the date of acquisition for business acquired during 2015. Assets and Liabilities Not Measured at Fair Value The carrying amounts of our accounts receivable, accounts payable, and other accrued liabilities approximate fair value due to their short maturities. |

Business Combinations [Abstract] | |
Business Acquisition | 6. Business Acquisition On January 16, 2015, we completed the acquisition of Detectent, Inc., or Detectent, a privately held corporation that provides customer intelligence solutions for utilities leveraging its data analytics platform, and paid $7.6 million in cash consideration. The acquisition of Detectent was accounted for under the acquisition method of accounting. Detectent’s SaaS, subscription, and software solutions help improve advanced metering infrastructure and utility grid operations, ensure revenue protection, and deliver enhanced customer engagement programs. We recorded goodwill of $4.5 million and intangible assets of $3.8 million, which consisted primarily of developed technology, customer relationships, non-compete agreements and order backlog, at the time of acquisition. The goodwill arising from the Detectent acquisition was largely attributable to the synergies expected to be realized and was not deductible for U.S. federal income tax purposes. In addition, we paid and held $4.0 million of deferred cash consideration, or contingent payments, in an escrow account, to be released over a two-year period subject to the retention of key employees of Detectent, or retention period. Contingent payments associated with future employment conditions are being recorded as compensation expense over the retention period. During the nine months ended September 30, 2016, we released $1.0 million from the escrow account in connection with the satisfaction of the retention terms of the acquisition agreement. |

Goodwill And Intangible Assets Disclosure [Abstract] | |
Goodwill and Intangible Assets | 7. Goodwill and Intangible Assets Goodwill: As of September 30, 2016 and December 31, 2015, the gross amount of goodwill was $8.8 million. In accordance with its accounting policy and ASC 350, we test our goodwill and any other intangibles with indefinite lives annually for impairment and assess whether there are any indicators of impairment on an interim basis. We operate in one reportable segment and we are organized as one reporting unit. We performed our annual impairment test for all reporting units on August 1, 2016 in accordance with its accounting policy and concluded that there was no impairment to goodwill during the nine months period ended September 30, 2016. Intangible Assets: The following table summarizes the gross carrying amount and accumulated amortization for the intangible assets resulting from acquisitions (in thousands): As of September 30, 2016 As of December 31, 2015 Useful Lives (in years) Gross Carrying Amount Accumulated Amortization Impairment Net Book Value Gross Carrying Amount Accumulated Amortization Impairment Net Book Value Purchased technology 4-6 years $ 4,865 $ 2,623 $ 882 $ 1,360 $ 4,865 $ 2,180 $ — $ 2,685 Customer relationships 4-7 years 3,640 1,461 1,322 857 3,640 973 — 2,667 Trade name 6 years 369 162 — 207 369 103 — 266 Total $ 8,874 $ 4,246 $ 2,204 $ 2,424 $ 8,874 $ 3,256 $ — $ 5,618 Intangible assets subject to amortization are amortized over their useful lives as shown in the table above. During the three months ended September 30, 2016, we determined that there were indicators of impairment for intangible assets which were acquired as part of our acquisition of Streetlight.Vision SAS. These resulted from a change of our monetization plans including a business model shift from on-time, lower-margin, third-party product shipments to higher-margin recurring managed services and SaaS billings. As a result, the impairment analysis for these intangible assets resulted in an impairment charge to operating expense of $2.2 million which was recorded in our consolidated statements of operations for the three and nine months ended September 30, 2016 . The following table illustrates the amortization expense included in the consolidated statements of operations for the three and nine months ended September 30, 2016 and 2015 (in thousands): Three Months Ended September 30, Nine Months Ended September 30, Amortization of purchased intangible assets: 2016 2015 2016 2015 Cost of revenue $ 79 $ 260 $ 443 $ 782 Sales and marketing 106 153 521 447 General and administrative 8 8 25 23 Total $ 193 $ 421 $ 989 $ 1,252 The estimated future amortization expense of purchased intangible assets with definite lives for the next five years is as follows (in thousands): Year Ending December 31, Amount Remainder of 2016 $ 192 2017 770 2018 738 2019 378 2020 335 2021 and thereafter 11 $ 2,424 |

Stock-Based Compensation | 8. Stock-Based Compensation Equity Incentive Plan and Employee Stock Purchase Plan Our Board of Directors adopted the 2012 Equity Incentive Plan, or 2012 Plan, which became effective on March 12, 2013 and serves as the successor to our 2003 Stock Option Plan, or 2003 Plan. Pursuant to the 2012 Plan, 3,400,000 shares of our common stock were initially reserved for grant, plus (1) any shares that were reserved and available for issuance under the 2003 Plan at the time the 2012 Plan became effective, and (2) any shares that become available upon forfeiture or repurchase by us under the 2003 Plan and a stock option plan assumed in connection with a previous acquisition, will be reserved for issuance. In addition, the number of shares of our common stock available for grant and issuance shall be increased on January 1 of each calendar year during the term of the Plan by the lesser of (i) four percent (4%) of the number of shares of our common stock issued and outstanding on each December 31 immediately prior to the date of increase, or (ii) such number of shares determined by the Board of Directors. Under the 2012 Plan, we may grant both incentive and non-statutory stock options, restricted stock, restricted stock units, and performance stock units to employees, directors and service providers. We may grant options to purchase shares of common stock to employees, directors and service providers at prices not less than the fair market value on the date of grant for both Incentive Stock Options, or ISOs, and Nonqualified Stock Options. ISOs granted to a person who, at the time of the grant, owns more than 10% of the voting power of all classes of stock must be at no less than 110% of the fair market value and expire five years from the date of grant. All other options generally have a contractual term of 10 years. Options generally vest over four years. RSUs generally vest between two to four years. PSUs generally vest over three years. Our Board of Directors adopted the ESPP, which became effective on March 12, 2013, pursuant to which 400,000 shares of our common stock have been reserved for future issuance. In addition, on each January 1 for the first ten calendar years after the first Offering Date, the aggregate number of shares of our common stock reserved for issuance under the ESPP shall be increased automatically by the number of shares equal to 1% of the total number of outstanding shares of our common stock on the immediately preceding December 31 subject to restrictions defined in the ESPP. Eligible employees can enroll and elect to contribute up to 15% of their compensation through payroll withholdings in each offering period, subject to certain limitations. Each offering period is six months in duration. The purchase price of the stock is the lower of 85% of the fair market value on (a) the first day of the offering period or (b) the purchase date. Inducement Grants On July 6, 2016, we entered into an employment agreement with Aysegul Ildeniz as our Chief Operating Officer, or COO. In connection with her employment, we granted Ms. Ildeniz a stock option to purchase 120,000 shares of our common stock, and RSUs that may be settled for 80,000 shares of our common stock, as inducement grants made outside of the 2012 Plan in reliance upon NYSE Rule 303A.08. The stock option has an exercise price equal to the closing market value of our common stock on the date of grant, and vests (i) with respect to 25% of the underlying shares on the one-year anniversary of the date of grant, and (ii) with respect to an additional 1/48th of the underlying shares each month thereafter, until such time as the option is fully vested and exercisable. The RSUs vest (i) with respect to 25% of the shares on the one-year anniversary of the date of grant, and (ii) with respect to an additional 1/16th of the shares on each three-month anniversary thereafter, until such time as the RSUs are fully vested . As of September 30, 2016 and December 31, 2015, there were 5.9 million and 4.9 million shares, respectively, of common stock reserved for future grants under our ESPP and 2012 Plan.

Commitments and Contingencies | 12. Commitments and contingencies Operating and Capital Leases Our primary operating lease commitment as of September 30, 2016, related to our headquarters in San Jose, California, requires monthly lease payments through September 2026. We recognize rent expense on a straight-line basis over the lease period. Where leases contain escalation clauses, rent abatements, or concessions, such as rent holidays and landlord or tenant incentives or allowances, we apply them in the determination of straight-line rent expense over the lease term. Rent expense for all facility leases was $1.8 million and $1.4 million for the three months ended September 30, 2016 and 2015, respectively, and $6.1 million and $3.9 million for the nine months ended September 30, 2016 and 2015, respectively. As of September 30, 2016, the future minimum commitments under our operating leases were as follows (in thousands): Operating Leases Remainder of 2016 $ 1,619 2017 7,746 2018 7,862 2019 7,541 2020 7,289 2021 and thereafter 41,539 Net minimum lease payments $ 73,596 Legal Contingencies EON Patent Litigation . In June 2011, EON Corp. IP Holdings, LLC, a non-producing entity, or EON, filed suit in United States District Court for the Eastern District of Texas, Tyler Division against us and a number of smart grid providers. The lawsuit alleges infringement of United States Patent Nos. 5,388,101, 5,481,546, and 5,592,491, or the EON Patents, by certain networking technology and services that we and the other defendants provide. Other defendants included Landis+Gyr AG (which was acquired by Toshiba Corporation), Aclara Power-Line Systems Inc., Elster Solutions, LLC, Itron, Inc. and Trilliant Networks Inc., all of which settled with EON prior to trial. We filed answers, affirmative defenses and counterclaims denying the plaintiff’s allegations and asserting that the plaintiff’s patents are invalid. A trial was held in June 2014. After the trial, the jury determined that we had infringed certain, but not all, of the claims under the EON Patents, and returned a verdict against us in the amount of $18.8 million. Following post-trial motions by both parties, the court reduced the damage award to approximately $13.0 million, and in December 2014, entered a final judgment in that amount plus approximately $1.5 million in pre-judgment interest. The court subsequently revised the final judgment to include additional costs of about $0.2 million and entered an amended final judgment in December 2014. All of the EON Patents have expired and therefore EON is not seeking, and EON may not recover, any additional sums as royalties for our sales of products going forward. In December 2014, we filed a notice of appeal with the U.S. Court of Appeals for the Federal Circuit in Washington, D.C. In order to stay the execution of the final judgment pending the appeal, in December 2014 we filed a surety bond in the amount of $17.6 million, which includes an additional 20% of the final judgment for post-judgment interest and expenses expected to be incurred during the appeal process, in accordance with court rules. The bond was issued by Zurich Insurance and is collateralized with a standby letter of credit in the amount of $13.0 million, the amount of the damage award, as described below in “ Customer Performance and Other Commitments.” en banc Linex Patent Litigation . In March 2013, Linex Technologies, Inc., a non-producing entity, or Linex, filed suit against us in United States District Court for the Southern District of Florida. Linex alleged that certain of our networking technology infringes United States Patent Nos. 6,493,377 and 7,167,503. We filed an answer in May 2013. In January 2014, the court granted the plaintiff’s request for a stay of the matter, pending reexamination of the patents at issue by the USPTO. In September 2014, Linex amended certain patent claims and canceled certain other patent claims based upon the USPTO’s completed reexaminations, and in October 2014, the court lifted the stay of the matter. In January 2015, Linex filed an amended complaint to incorporate facts related to the completed reexaminations, and we filed an answer responding to the complaint and raising additional defenses. In June 2015, the court stayed the action pending the USPTO’s completion of further ex parte reexaminations of the patents at issue. We believe that we have meritorious defenses to Linex’s allegations and intend to continue vigorously defending against the action. Atlas/ComEd, Atlas/PG&E, and Atlas/FP&L Patent Litigation . In November 2015, Atlas IP, LLC filed separate suits against our customers Commonwealth Edison Company, or ComEd, and Pacific Gas and Electric Co., or PG&E, alleging infringement of United States Patent No. 5,371,734 by communications between smart meters and access points over a neighborhood area network using wireless communication modules and networking equipment supplied by us. In May 2016, Atlas filed a similar suit against our customer Florida Power & Light Company, or FP&L. We have agreed to assume the defense in each of these suits. ComEd PG&E . FP&L . We believe that we have meritorious defenses to Atlas IP’s allegations in each of these matters, and intend to continue vigorously defending the actions. Acoustic Technology Patent Litigation. In July 2016, Acoustic Technology, Inc., a non-producing entity, filed suit in United States District Court for the Eastern District of Texas, Marshall Division against us. The lawsuit alleges infringement of United States Patent Nos. 5,986,574, and 6,509,841 by certain meters and networking technology and services that we provide. The patents will expire in late 2017 and early 2018. We filed a motion to dismiss, as well as a motion to transfer the matter to the Northern District of California, in September 2016. We believe that we have meritorious defenses to Acoustic’s allegations and intend to vigorously defend ourselves. GroupChatter/GE Patent Litigation . In November 2015, GroupChatter, LLC, or GroupChatter, filed suit in United States District Court for the Eastern District of Texas, against General Electric Company, GE Energy Management Services, Inc. and GE Grid Solutions, LLC (collectively, “GE”), alleging infringement of United States Patent Nos. 7,969,959, 8,199,740, 8,588,207, 9,014,659 and 9,294,888, by certain systems that include wireless communication-enabled meters produced by GE, some of which include our wireless modules. GE has requested that we indemnify them in connection with the GroupChatter suit. We have denied the request. In addition to the matters described above, from time to time we may be subject to other legal proceedings and claims in the ordinary course of business. We have received, and may in the future continue to receive, claims from third parties asserting infringement of their intellectual property rights. We may, from time to time, also be subject to various legal or government claims, disputes, or investigations. Such matters may include, but not be limited to, claims, disputes, or investigations related to warranty, refund, breach of contract, employment, intellectual property, government regulation, compliance or other matters. Future litigation may be necessary to defend ourselves and our customers by determining the scope, enforceability and validity of third-party rights or to establish our rights. There can be no assurance with respect to the outcome of any current or future litigation brought against us or pursuant to which we have indemnification obligations and the outcome could have a material adverse impact on our business, operating results and financial condition. We have not recorded any amounts for contingent losses associated with the matters described above based on our belief that losses, while reasonably possible, are not probable. Unless otherwise stated, we are currently unable to predict the final outcome of these lawsuits and therefore cannot determine the likelihood of loss nor estimate a range of possible loss. We are directly involved with various unresolved legal actions and claims, and are indirectly involved with proceedings by administrative bodies such as public utility commissions, arising in the ordinary course of business. We do not believe that any liability from any reasonably foreseeable disposition of such legal actions and claims, individually or in the aggregate, would have a material effect on our consolidated financial statements. There are many uncertainties associated with any litigation or claim, and we cannot be certain that these actions or other third-party claims will be resolved without costly litigation, fines and/or substantial settlement payments. If that occurs, our business, financial condition and results of operations could be materially and adversely affected. If information becomes available that causes us to determine that a loss in any of our pending litigation matters, claims or settlements is probable, and a reasonable estimate of the loss associated with such events can be made, we will record the estimated loss at that time. Customer Performance and Other Commitments Certain customer agreements require us to obtain letters of credit or surety bonds in support of our obligations under such arrangements. These letters of credit or surety bonds typically provide a guarantee to the customer for future performance, which usually covers the deployment phase of a contract and may on occasion cover the operations and maintenance phase of service contracts. As of September 30, 2016 and December 31, 2015, we had a total of $13.9 million and $22.7 million, respectively, of standby letters of credit issued under a credit facility with a financial institution. As of September 30, 2016 and December 31, 2015, $4.6 million (AUD $6.2 million) and $4.4 million (AUD $6.2 million) of these standby letters of credit were denominated in Australian dollars, respectively. In accordance with the terms of our credit facility, increases or decreases in the exchange rate between the Australian dollar and the U.S. dollar will increase or decrease the amount available to us under the credit facility. On December 18, 2015, we entered into a senior secured credit facilities credit agreement, or Credit Facility, with Silicon Valley Bank and HSBC Bank USA, National Association, or HSBC, which provides a revolving loan facility in an aggregate amount not to exceed $75.0 million with an available letter of credit sub-facility in the aggregate amount of $75.0 million and an available swingline sub-facility in the aggregate amount of $5.0 million. As of September 30, 2016, there were no borrowings outstanding under the Credit Facility; however, this line of credit is backing $13.9 million of letters of credit, leaving $61.1 million of available capacity for cash borrowings or additional letters of credit or swingline loan, subject to compliance with financial covenants and other customary conditions to borrowings, which varies at each period end. As of September 30, 2016, we were in compliance with the financial covenants in the credit agreement. As of September 30, 2016, we had a $20.3 million unsecured surety bond. The surety bond provides a financial guarantee to support performance obligations under certain customer agreements. In the event any such letters of credit or surety bonds are called, we would be obligated to reimburse the issuer of the letters of credit or surety bond. We do not believe there will be any claims against currently outstanding letters of credit or surety bonds. Indemnification Commitments Directors, Officers and Employees . In accordance with our bylaws and/or pursuant to indemnification agreements we have entered into with directors, officers and certain employees, we have indemnification obligations to our directors, officers and employees for claims brought against these persons arising out of certain events or occurrences while they are serving at our request in such a capacity. We maintain a director and officer liability insurance coverage to reduce our exposure to such obligations, and payments made under these agreements. To date, there have been no indemnification claims by these directors, officers and employees . Customers and Third Party Device Manufacturers . Refer to the discussion above under the heading Legal Contingencies for a description of our indemnification obligations. Our contracts with customers and third party device manufacturers typically provide indemnification for claims filed by third parties alleging that our products and services sold to the customer or manufacturer infringe or misappropriate any patent, copyright, trademark or other intellectual property right. In our customer contracts, we also typically provide an indemnification for third-party claims resulting from death, personal injury or property damage caused by the negligence or willful misconduct of our employees and agents in connection with the performance of certain contracts. Under our customer and third party device manufacturer indemnities, we typically agree to defend the utility customer or third party device manufacturer, as the case may be, from such claims, and pay any resulting costs, damages and attorneys’ fees awarded against the indemnified party with respect to such claims, provided that (a) the indemnified party promptly notifies us in writing of the claim, (b) the indemnified party provides reasonable assistance to us at our expense, and (c) we have sole control of the defense and all related settlement negotiations. |
