Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Basis of Historical Presentation The unaudited interim condensed consolidated financial statements of AbbVie Inc. (AbbVie or the company) have been prepared pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) have been omitted. These unaudited interim condensed consolidated financial statements should be read in conjunction with the company’s audited consolidated financial statements and notes included in the company’s Annual Report on Form 10-K for the year ended December 31, 2020. It is management’s opinion that these financial statements include all normal and recurring adjustments necessary for a fair presentation of the company’s financial position and operating results. Net revenues and net earnings for any interim period are not necessarily indicative of future or annual results. Certain reclassifications were made to conform the prior period interim condensed consolidated financial statements to the current period presentation. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements ASU No. 2019-12 In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) . The standard includes simplifications related to accounting for income taxes including removing certain exceptions related to the approach for intraperiod tax allocation and the recognition of deferred tax liabilities for outside basis differences. The standard also clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. AbbVie adopted the standard in the first quarter of 2021. The adoption did not have a material impact on its consolidated financial statements.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per ShareAbbVie grants certain restricted stock units (RSUs) that are considered to be participating securities. Due to the presence of participating securities, AbbVie calculates earnings per share (EPS) using the more dilutive of the treasury stock or the two-class method. For all periods presented, the two-class method was more dilutive. The following table summarizes the impact of the two-class method: Three months ended Six months ended (in millions, except per share data) 2021 2020 2021 2020 Basic EPS Net earnings (loss) attributable to AbbVie Inc. $ 766 $ (738) $ 4,319 $ 2,272 Earnings allocated to participating securities 17 18 34 28 Earnings (loss) available to common shareholders $ 749 $ (756) $ 4,285 $ 2,244 Weighted-average basic shares outstanding 1,769 1,647 1,769 1,564 Basic earnings (loss) per share attributable to AbbVie Inc. $ 0.42 $ (0.46) $ 2.42 $ 1.44 Diluted EPS Net earnings (loss) attributable to AbbVie Inc. $ 766 $ (738) $ 4,319 $ 2,272 Earnings allocated to participating securities 17 18 34 28 Earnings (loss) available to common shareholders $ 749 $ (756) $ 4,285 $ 2,244 Weighted-average shares of common stock outstanding 1,769 1,647 1,769 1,564 Effect of dilutive securities 7 — 7 4 Weighted-average diluted shares outstanding 1,776 1,647 1,776 1,568 Diluted earnings (loss) per share attributable to AbbVie Inc. $ 0.42 $ (0.46) $ 2.41 $ 1.43 Certain shares issuable under stock-based compensation plans were excluded from the computation of EPS because the effect would have been antidilutive. The number of common shares excluded was insignificant for all periods presented.

Licensing, Acquisitions, and Other Arrangements
Licensing, Acquisitions, and Other Arrangements	Licensing, Acquisitions and Other Arrangements Acquisition of Allergan The acquisition of Allergan was accounted for as a business combination using the acquisition method of accounting. The acquisition method requires, among other things, that assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date. The valuation of assets acquired and liabilities assumed was finalized during the three months ended June 30, 2021. Measurement period adjustments to the preliminary purchase price allocation during the six months ended June 30, 2021 included: (i) an increase to intangible assets of $710 million; (ii) an increase to deferred income tax liabilities of $148 million; (iii) other individually insignificant adjustments for a net increase to identifiable net assets of $2 million; and (iv) a corresponding decrease to goodwill of $564 million. The measurement period adjustments primarily resulted from the completion of the valuation of certain license agreement intangible assets based on facts and circumstances that existed as of the acquisition date and did not result from intervening events subsequent to such date. These adjustments did not have a significant impact on AbbVie's results of operations for the three and six months ended June 30, 2021 and would not have had a significant impact on prior period results if these adjustments had been made as of the acquisition date. Other Licensing & Acquisitions Activity Cash outflows related to other acquisitions and investments totaled $345 million for the six months ended June 30, 2021 and $192 million for the six months ended June 30, 2020. AbbVie recorded acquired in-process research and development (IPR&D) charges of $97 million for the three months and $167 million for the six months ended June 30, 2021 and recorded acquired IPR&D charges of $853 million for the three and six months ended June 30, 2020. TeneoOne and TNB-383B In June 2021, AbbVie exercised its exclusive right to acquire TeneoOne, an affiliate of Teneobio, Inc., and TNB-383B, a BCMA-targeting immunotherapeutic for the potential treatment of relapsed or refractory multiple myeloma (R/R MM). In February 2019, AbbVie and TeneoOne entered a strategic transaction to develop and commercialize TNB-383B, a bispecific antibody that simultaneously targets BCMA and CD3 and is designed to direct the body's own immune system to target and kill BCMA-expressing tumor cells. AbbVie exercised its exclusive right to acquire TeneoOne and TNB-383B based on an interim analysis of an ongoing Phase 1 study. Under the terms of the agreement, AbbVie will make a $400 million warrant exercise payment subject to adjustments for certain expenses. Closing of the transaction is subject to regulatory approval. AbbVie could make additional payments of up to $250 million upon the achievement of certain development, regulatory and commercial milestones. Soliton, Inc. In May 2021, AbbVie announced that it entered into a definitive agreement with Soliton, Inc. (Soliton) to acquire Soliton and RESONIC, its Rapid Acoustic Pulse device which recently received U.S. Food and Drug Administration (FDA) 510(k) clearance and is a non-invasive treatment for the short-term improvement in the appearance of cellulite.

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measures	Financial Instruments and Fair Value MeasuresRisk Management Policy See Note 11 to the company’s Annual Report on Form 10-K for the year ended December 31, 2020 for a summary of AbbVie’s risk management policy and use of derivative instruments. Financial Instruments Various AbbVie foreign subsidiaries enter into foreign currency forward exchange contracts to manage exposures to changes in foreign exchange rates for anticipated intercompany transactions denominated in a currency other than the functional currency of the local entity. These contracts, with notional amounts totaling $1.7 billion at June 30, 2021 and $1.5 billion at December 31, 2020, are designated as cash flow hedges and are recorded at fair value. The durations of these forward exchange contracts were generally less than 18 months. Accumulated gains and losses as of June 30, 2021 are reclassified from accumulated other comprehensive income (loss) (AOCI) and included in cost of products sold at the time the products are sold, generally not exceeding six months from the date of settlement. In the third quarter of 2019, the company entered into treasury rate lock agreements with notional amounts totaling $10.0 billion to hedge exposure to variability in future cash flows resulting from changes in interest rates related to the issuance of long-term debt in connection with the acquisition of Allergan. The treasury rate lock agreements were designated as cash flow hedges and recorded at fair value. The agreements were net settled upon issuance of the senior notes in November 2019 and the resulting net gain was recognized in other comprehensive income. This gain is reclassified to interest expense, net over the term of the related debt. The company is party to interest rate swap contracts designated as cash flow hedges with notional amounts totaling $1.5 billion at June 30, 2021 and $2.3 billion at December 31, 2020. The effect of the hedge contracts is to change a floating-rate interest obligation to a fixed rate for that portion of the floating-rate debt. Realized and unrealized gains or losses are included in AOCI and are reclassified to interest expense, net over the lives of the floating-rate debt. The company also enters into foreign currency forward exchange contracts to manage its exposure to foreign currency denominated trade payables and receivables and intercompany loans. These contracts are not designated as hedges and are recorded at fair value. Resulting gains or losses are reflected in net foreign exchange gain or loss in the condensed consolidated statements of earnings and are generally offset by losses or gains on the foreign currency exposure being managed. These contracts had notional amounts totaling $7.8 billion at June 30, 2021 and $8.6 billion at December 31, 2020. The company also uses foreign currency forward exchange contracts or foreign currency denominated debt to hedge its net investments in certain foreign subsidiaries and affiliates. The company had foreign currency forward exchange contracts with notional amounts totaling €2.8 billion at June 30, 2021 and €971 million at December 31, 2020. The company also had an aggregate principal amount of senior Euro notes designated as net investment hedges of €5.9 billion at June 30, 2021 and €6.6 billion at December 31, 2020. The company uses the spot method of assessing hedge effectiveness for derivative instruments designated as net investment hedges. Realized and unrealized gains and losses from these hedges are included in AOCI and the initial fair value of hedge components excluded from the assessment of effectiveness is recognized in interest expense, net over the life of the hedging instrument. The company is party to interest rate swap contracts designated as fair value hedges with notional amounts totaling $3.8 billion at June 30, 2021 and $4.8 billion December 31, 2020. The effect of the hedge contracts is to change a fixed-rate interest obligation to a floating rate for that portion of the debt. AbbVie records the contracts at fair value and adjusts the carrying amount of the fixed-rate debt by an offsetting amount. No amounts are excluded from the assessment of effectiveness for cash flow hedges or fair value hedges.

Related to AbbVie’s non-derivative, foreign currency denominated debt designated as net investment hedges, the company recognized in other comprehensive income pre-tax losses of $126 million for the three months and pre-tax gains of $256 million for the six months ended June 30, 2021 and pre-tax losses of $252 million for the three months and pre-tax losses of $192 million for the six months ended June 30, 2020.

The derivatives entered into by the company were valued using observable market inputs including published interest rate curves and both forward and spot prices for foreign currencies. The fair value measurements of the contingent consideration liabilities were determined based on significant unobservable inputs, including the discount rate, estimated probabilities and timing of achieving specified development, regulatory and commercial milestones and the estimated amount of future sales of the acquired products. The potential contingent consideration payments are estimated by applying a probability-weighted expected payment model for contingent milestone payments and a Monte Carlo simulation model for contingent royalty payments, which are then discounted to present value. Changes to the fair value of the contingent consideration liabilities can result from changes to one or a number of inputs, including discount rates, the probabilities of achieving the milestones, the time required to achieve the milestones and estimated future sales. Significant judgment is employed in determining the appropriateness of certain of these inputs. Changes to the inputs described above could have a material impact on the company's financial position and results of operations in any given period. The fair value of the company's contingent consideration liabilities as of June 30, 2021 was calculated using the following significant unobservable inputs: Range Weighted average (a) Discount rate 0.1% - 2.5% 1.4 % Probability of payment for unachieved milestones 56% - 92% 87 % Probability of payment for royalties by indication (b) 56% - 100% 95 % Projected year of payments 2021 - 2034 2027 (a) Unobservable inputs were weighted by the relative fair value of the contingent consideration liabilities. (b) Excluding approved indications, the estimated probability of payment ranged from 56% to 89% at June 30, 2021. There have been no transfers of assets or liabilities into or out of Level 3 of the fair value hierarchy. The following table presents the changes in fair value of total contingent consideration liabilities which are measured using Level 3 inputs: Six months ended (in millions) 2021 2020 Beginning balance $ 12,997 $ 7,340 Additions (a) — 121 Change in fair value recognized in net earnings 2,349 881 Payments (357) (129) Ending balance $ 14,989 $ 8,213 (a) Represents contingent consideration liabilities assumed in the Allergan acquisition. The change in fair value recognized in net earnings is recorded in other expense, net in the condensed consolidated statements of earnings. Certain financial instruments are carried at historical cost or some basis other than fair value.

The company records these investments at cost and remeasures them to fair value based on certain observable price changes or impairment events as they occur. The carrying amount of these investments was $118 million as of June 30, 2021 and $102 million as of December 31, 2020. No significant cumulative upward or downward adjustments have been recorded for these investments as of June 30, 2021. Concentrations of Risk Of total net accounts receivable, three U.S. wholesalers accounted for 73% as of June 30, 2021 and 72% as of December 31, 2020, and substantially all of AbbVie’s net revenues in the United States were to these three wholesalers. Humira (adalimumab) is AbbVie’s single largest product and accounted for approximately 37% of AbbVie’s total net revenues for the six months ended June 30, 2021 and 50% for the six months ended June 30, 2020. Debt and Credit Facilities In April 2021, the company repaid $1.8 billion aggregate principal amount of 2.3% senior notes that were scheduled to mature in May 2021. In May 2021, the company repaid €750 million aggregate principal amount of 0.5% senior euro notes that were scheduled to mature in June 2021. These repayments were made by exercising, under the terms of the notes, 30-day early redemptions at 100% of the principal amounts. The company also repaid $750 million aggregate principal amount of floating rate senior notes at maturity in May 2021. In connection with the acquisition of Allergan, in May 2020, the company borrowed $3.0 billion under a $6.0 billion term loan credit agreement, consisting of a $1.0 billion floating rate three-year term loan tranche and a $2.0 billion floating rate five-year term loan tranche. Subsequent to these borrowings, AbbVie terminated the unused commitments of the lenders under the term loan. In May 2020, AbbVie completed its previously announced offers to exchange any and all outstanding notes of certain series issued by Allergan for new notes to be issued by AbbVie and cash. Following the settlement of the exchange offers, AbbVie issued $14.0 billion and €3.1 billion of new notes in exchange for the Allergan notes tendered in the exchange offers. The aggregate principal amount of Allergan notes that remained outstanding following the settlement of the exchange offers was approximately $1.5 billion and €635 million. The exchange transaction was accounted for as a modification of the assumed debt instruments. In May 2020, the company also repaid $3.8 billion aggregate principal amount of 2.5% senior notes at maturity. Short-Term Borrowings There were no commercial paper borrowings outstanding as of June 30, 2021 and December 31, 2020. There were no commercial paper borrowings issued during the six months ended June 30, 2021.

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe effective tax rate was 34% for the three months and 14% for the six months ended June 30, 2021 compared to 7% income tax expense on pre-tax loss for the three months ended June 30, 2020 and 6% income tax expense on pre-tax income for the six months ended June 30, 2020. The effective tax rate in each period differed from the U.S. statutory tax rate of 21% principally due to the benefit from foreign operations which reflects the impact of lower income tax rates in locations outside the United States, tax incentives in Puerto Rico and other foreign tax jurisdictions and business development activities. The increase in the effective tax rate for the three and six months ended June 30, 2021 over the prior year was primarily due to accretion on contingent consideration in 2021 as well as non-deductible Allergan acquisition related expenses and a change in tax rate in a foreign jurisdiction in 2020.Due to the potential for resolution of federal, state and foreign examinations and the expiration of various statutes of limitations, it is reasonably possible that the company’s gross unrecognized tax benefits balance may change within the next 12 months by up to $116 million.

Legal Proceedings and Contingen

Legal Proceedings and Contingencies	6 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Contingencies	Legal Proceedings and Contingencies AbbVie is subject to contingencies, such as various claims, legal proceedings and investigations regarding product liability, intellectual property, commercial, securities and other matters that arise in the normal course of business. The most significant matters are described below. Loss contingency provisions are recorded for probable losses at management’s best estimate of a loss, or when a best estimate cannot be made, a minimum loss contingency amount within a probable range is recorded. Initiation of new legal proceedings or a change in the status of existing proceedings may result in a change in the estimated loss accrued by AbbVie. While it is not feasible to predict the outcome of all proceedings and exposures with certainty, management believes that their ultimate disposition should not have a material adverse effect on AbbVie’s consolidated financial position, results of operations or cash flows.Subject to certain exceptions specified in the separation agreement by and between Abbott Laboratories (Abbott) and AbbVie, AbbVie assumed the liability for, and control of, all pending and threatened legal matters related to its business, including liabilities for any claims or legal proceedings related to products that had been part of its business, but were discontinued prior to the distribution, as well as assumed or retained liabilities, and will indemnify Abbott for any liability arising out of or resulting from such assumed legal matters. Antitrust Litigation Lawsuits are pending against AbbVie and others generally alleging that the 2005 patent litigation settlement involving Niaspan entered into between Kos Pharmaceuticals, Inc. (a company acquired by Abbott in 2006 and presently a subsidiary of AbbVie) and a generic company violates federal and state antitrust laws and state unfair and deceptive trade practices and unjust enrichment laws. Plaintiffs generally seek monetary damages and/or injunctive relief and attorneys' fees. The lawsuits pending in federal court consist of four individual plaintiff lawsuits and two consolidated purported class actions: one brought by Niaspan direct purchasers and one brought by Niaspan end-payers. The cases are pending in the United States District Court for the Eastern District of Pennsylvania for coordinated or consolidated pre-trial proceedings under the MDL Rules as In re: Niaspan Antitrust Litigation , MDL No. 2460. In August 2019, the court certified a class of direct purchasers of Niaspan. In June 2020, the court denied the end-payers' motion to certify a class. In October 2016, the Orange County, California District Attorney’s Office filed a lawsuit on behalf of the State of California regarding the Niaspan patent litigation settlement in Orange County Superior Court, asserting a claim under the unfair competition provision of the California Business and Professions Code seeking injunctive relief, restitution, civil penalties and attorneys’ fees. In September 2014, the Federal Trade Commission (FTC) filed a lawsuit, FTC v. AbbVie Inc., et al. , against AbbVie and others in the United States District Court for the Eastern District of Pennsylvania, alleging that 2011 patent litigation with two generic companies regarding AndroGel was sham litigation and the settlements of that litigation violated federal antitrust law. In May 2015, the court dismissed the FTC’s settlement-related claim. In June 2018, following a bench trial, the court found for the FTC on its sham litigation claim and ordered a disgorgement remedy of $448 million, plus prejudgment interest. The court denied the FTC’s request for injunctive relief. In September 2020, the United States Court of Appeals for the Third Circuit reversed the district court’s finding of sham litigation with respect to one generic company and affirmed with respect to the other but held the FTC lacked authority to obtain a disgorgement remedy and vacated the district court’s award. The Third Circuit also affirmed the district court’s denial of the FTC’s injunction request and reinstated the FTC’s settlement-related claim for further proceedings in the district court. In August 2019, direct purchasers of AndroGel filed a lawsuit, King Drug Co. of Florence, Inc., et al. v. AbbVie Inc., et al. , against AbbVie and others in the United States District Court for the Eastern District of Pennsylvania, alleging that 2006 patent litigation settlements and related agreements by Solvay Pharmaceuticals, Inc. (a company Abbott acquired in February 2010 and now known as AbbVie Products LLC) with three generic companies violated federal antitrust law, and also making allegations similar to those in FTC v. AbbVie Inc. (above). In May 2020, Perrigo Company and related entities filed a lawsuit against AbbVie and others in the United States District Court for the Eastern District of Pennsylvania, making sham litigation allegations similar to those in FTC v. AbbVie Inc . (above). In October 2020, the Perrigo lawsuit was transferred to the United States District Court for New Jersey. Between March and May 2019, 12 putative class action lawsuits were filed in the United States District Court for the Northern District of Illinois by indirect Humira purchasers, alleging that AbbVie’s settlements with biosimilar manufacturers and AbbVie’s Humira patent portfolio violated state and federal antitrust laws. The court consolidated these lawsuits as In re: Humira (Adalimumab) Antitrust Litigation . In June 2020, the court dismissed the consolidated litigation with prejudice. The plaintiffs have appealed the dismissal. Lawsuits are pending against Forest Laboratories, LLC and others generally alleging that 2009 and 2010 patent litigation settlements involving Namenda entered into between Forest and generic companies and other conduct by Forest involving Namenda, violated state antitrust, unfair and deceptive trade practices, and unjust enrichment laws. Plaintiffs generally seek monetary damages, injunctive relief and attorneys’ fees. The lawsuits, purported class actions filed by indirect purchasers of Namenda, are consolidated as In re: Namenda Indirect Purchaser Antitrust Litigation in the United States District Court for the Southern District of New York. Lawsuits are pending against Allergan Inc. generally alleging that Allergan’s petitioning to the U.S. Patent Office and Food and Drug Administration and other conduct by Allergan involving Restasis violated federal and state antitrust laws and state unfair and deceptive trade practices and unjust enrichment laws. Plaintiffs generally seek monetary damages, injunctive relief and attorneys’ fees. The lawsuits, certified as a class action filed on behalf of indirect purchasers of Restasis, are consolidated for pre-trial purposes in the United States District Court for the Eastern District of New York under the MDL Rules as In re: Restasis (Cyclosporine Ophthalmic Emulsion) Antitrust Litigation , MDL No. 2819. In May 2021, the parties reached an agreement in principle to settle this matter that, once finalized, will be subject to court approval. Lawsuits are pending against Forest Laboratories, LLC and others generally alleging that 2012 and 2013 patent litigation settlements involving Bystolic with six generic manufacturers violated federal and state antitrust laws and state unfair and deceptive trade practices and unjust enrichment laws. Plaintiffs generally seek monetary damages, injunctive relief, and attorneys’ fees. The lawsuits, purported class actions filed on behalf of direct and indirect purchasers of Bystolic, are consolidated as In re: Bystolic Antitrust Litigation in the United States District Court for the Southern District of New York. Government Proceedings Lawsuits are pending against Allergan and other defendants generally alleging that they improperly marketed and/or distributed prescription opioid products. Approximately 3,100 matters are pending against Allergan. The federal court cases are consolidated for pre-trial purposes in the United States District Court for the Northern District of Ohio under the MDL rules as In re: National Prescription Opiate Litigation , MDL No. 2804. Approximately 300 of the claims are pending in various state courts. The plaintiffs in these cases, which include states, counties, cities, school districts, hospitals, union trust funds and third-party payors, generally seek compensatory and punitive damages. In July 2019, the New Mexico Attorney General filed a lawsuit, State of New Mexico ex rel. Balderas v. AbbVie Inc., et al. , in New Mexico District Court for Santa Fe County against AbbVie and other companies alleging their marketing of AndroGel violated New Mexico’s Unfair Practices Act. In October 2020, the state added a claim under the New Mexico False Advertising Act. Shareholder and Securities Litigation In June 2016, a lawsuit, Elliott Associates, L.P., et al. v. AbbVie Inc. , was filed by five investment funds against AbbVie in the Cook County, Illinois Circuit Court alleging that AbbVie made misrepresentations and omissions in connec tion with its proposed t ransaction with Shire. Similar lawsuits were filed between July 2017 and October 2019 against AbbVie and in some instances its chief executive officer in the same court by additional investment funds. The court granted motions dismissing the claims of three investment-fund plaintiffs, which they appealed. In March 2021, in the first of those appeals, the dismissal was affirmed. One of these plaintiffs refiled its lawsuit in New York state court in June 2020 while the appeal of its dismissal in Illinois is pending. In November 2020, the New York Supreme Court for the County of New York dismissed that lawsuit, which is being appealed. Plaintiffs seek compensatory and punitive damages. In October 2018, a federal securities purported class action lawsuit, Holwill v. AbbVie Inc., et al ., was filed in the United States District Court for the Northern District of Illinois against AbbVie, its chief executive officer and former chief financial officer, alleging that reasons stated for Humira sales growth in financial filings between 2013 and 2017 were misleading because they omitted alleged misconduct in connection with Humira patient and reimbursement support services and other services and items of value that allegedly induced Humira prescriptions. Lawsuits are pending against Allergan and certain of its current and former officers alleging they made misrepresentations and omissions regarding Allergan's textured breast implants. The lawsuits, which were filed by Allergan shareholders, have been consolidated in the United States District Court for the Southern District of New York as In re: Allergan plc Securities Litigation . The plaintiffs generally seek compensatory damages and attorneys’ fees. In September 2019, the court partially granted Allergan's motion to dismiss. In September 2020, the court denied plaintiffs’ class certification motion because it found the lead plaintiff to be an inadequate representative of the proposed class but allowed another putative class member to propose itself as a new lead plaintiff. In December 2020, the court appointed a new lead plaintiff. Lawsuits are pending against Allergan and certain of its current and former officers alleging they made misrepresentations and omissions regarding Allergan’s former Actavis generics unit and its alleged anticompetitive conduct with other generic drug companies. The lawsuits were filed by Allergan shareholders and consist of three purported class actions and one individual action seeking monetary damages and attorney’s fees that have been consolidated in the U.S. District Court for the District of New Jersey as In re: Allergan Generic Drug Pricing Securities Litigation . In July 2021, the parties reached an agreement to settle the class action lawsuits, which is pending court approval. Product Liability and General Litigation In 2018, a qui tam lawsuit, U.S. ex rel. Silbersher v. Allergan Inc., et al. , was filed in the United States District Court for the Northern District of California against several Allergan entities and others, alleging that their conduct before the U.S. Patent Office resulted in false claims for payment being made to federal and state healthcare payors for Namenda XR and Namzaric. The plaintiff-relator seeks damages and attorneys' fees under the federal False Claims Act and state law analogues. The federal government and state governments declined to intervene in the lawsuit. Intellectual Property Litigation AbbVie Inc. and AbbVie Biotechnology Ltd are seeking to enforce their patent rights relating to adalimumab (a drug Abb V ie sells under the trademark Humira). In April 2021 and May 2021, cases were filed in the United States District Court for the Northern District of Illinois against Alvotech hf. AbbVie alleges defendant’s proposed biosimilar adalimumab product infringes certain AbbVie patents and seeks declaratory and injunctive relief. Defendant has filed a motion to dismiss the April 2021 case on jurisdictional grounds. In May 2021, Alvotech hf. and its U . S . subsidiary Alvotech USA, Inc. filed a declaratory judgment action in the United States Eastern District of Virginia seeking a declaration that the same patents at issue in AbbVie’s April 2021 Illinois case are invalid or not infringed. AbbVie has filed a motion to dismiss or transfer that case to the Northern District of Illinois. Pharmacyclics LLC, a wholly owned subsidiary of AbbVie, is seeking to enforce its patent rights relating to ibrutinib tablets (a drug Pharmacyclics sells under the trademark Imbruvica). Cases were filed in the United States District Court for the District of Delaware in March 2019 and March 2020 against Alvogen Pine Brook LLC and Natco Pharma Ltd. Pharmacyclics alleges defendants’ proposed generic ibrutinib tablet product infringes certain Pharmacyclics patents and seeks declaratory and injunctive relief. Janssen Biotech, Inc. which is in a global collaboration with Pharmacyclics concerning the development and marketing of Imbruvica, is the co-plaintiff in these suits.
