The Skinny Label That Wasn’t—Federal Circuit Reinstates Induced Infringement Verdict

The US Court of Appeals for the Federal Circuit vacated the district court’s grant of judgment as a matter of law (JMOL) of non-infringement where substantial evidence supported the jury’s verdict of induced infringement by an attempted “skinny label” that nonetheless encouraged doctors to engage in a patented use. GlaxoSmithKline LLC v. Teva Pharmaceuticals USA, Inc., Case Nos. 18-1876, -2023 (Fed. Cir. Aug. 5, 2021) (Moore, C.J.) (Prost, J., dissenting).

GlaxoSmithKline LLC (GSK) sells a drug called carvedilol (brand name Coreg®), which is approved for three indications: Hypertension, congestive heart failure (CHF) and left ventricular dysfunction following a myocardial infarction (post-MI LVD). In 2002, Teva filed an abbreviated new drug application (ANDA) for US Food and Drug Administration (FDA) approval of its generic carvedilol for all three indications. At that time, GSK’s patent on the carvedilol compound was still in force; Teva certified that it would not launch its product until the patent expired in 2007. GSK also had a second patent on a method of treating CHF using carvedilol and a second agent. In 2002, Teva sent GSK a Paragraph IV notice contending that the claims of that patent were invalid over prior art. Rather than sue Teva, GSK applied for reissue of the patent. In 2004, Teva received FDA “tentative approval” for its ANDA “for the treatment of heart failure and hypertension,” which was to become effective at the expiry of the compound patent in 2007.

In January 2008, the method-of-use patent reissued with claims directed to a method of decreasing mortality caused by CHF by administering carvedilol with at least one other therapeutic agent. Just before its launch in 2007, Teva certified to the FDA that its label would not include the indication listed in the Orange Book as covered by the original method-of-use patent (i.e., “decreasing mortality caused by congestive heart failure”), and thus included only the hypertension and post-MI LVD indications. Teva’s press releases stated that its generic carvedilol was “indicated for treatment of heart failure and hypertension.” In 2011, the FDA asked Teva to revise its labeling to be identical with GSK’s. Teva obliged (listing again the CHF indication) and took the position that it did not need to provide certification for the reissued patent because it received final approval of its ANDA before the patent reissued. GSK sued.

GSK won a jury verdict that the challenged patents had not been shown to be invalid and that Teva was liable for induced infringement. At trial, GSK contended—and the jury heard evidence—that post-MI LVD is a form (and fell within the Court’s construction) of CHF such that Teva’s attempted skinny label nonetheless encouraged doctors to engage in a patented use. After trial, however, the district court granted JMOL of non-infringement because the CHF and post-MI LVD indications were different. On appeal, the Federal Circuit found that substantial evidence supported the implied jury, finding that post-MI LVD is a form of CHF such that the label with the post-MI LVD indication induced infringement of the reissued [...]

Tax Court Allows Partial Deduction, Requires Partial Capitalization of Generic Drug Approval Legal Expenses

The US Tax Court determined that a pharmaceutical manufacturer’s legal expenses incurred to defend against a patent infringement suit were eligible for an immediate deduction as ordinary and necessary business expenses, while legal expenses incurred as part of an abbreviated new drug application (ANDA) were not eligible for an immediate deduction and thus had to be capitalized and then amortized over 15 years. Mylan, Inc. & Subsidiaries v. Commissioner, 156 T.C. No. 10 (Apr. 27, 2021) (Urda, J.)

The ANDA process allows for faster approval of a generic drug if the manufacturer can show that the generic drug is sufficiently similar to an approved brand name drug. As part of the ANDA process, the generic manufacturer must file statements certifying that the generic drug does not infringe any brand drug patents, or that such patents are invalid. The generic manufacturer also must send a notification to the holder of any patents covered by the certification statements.

Mylan filed several ANDAs for generic versions of brand name drugs, including Celebrex, Lunesta and Nexium, during the tax years at issue in the case. Considerable legal expenses were incurred as part of filing the ANDAs and making the required certifications and notifications. As a result of those certifications and notifications, patent holders brought approximately 120 patent infringement suits against Mylan. Mylan defended itself against the infringement suits, incurring litigation expenses.

In general, taxpayers may take an immediate deduction for ordinary and necessary business expenses. However, taxpayers must capitalize expenditures that create or enhance a distinct asset or otherwise generate benefits for taxpayers beyond a single tax year. Special rules apply to determine whether expenses related to an intangible asset should be capitalized. The income tax regulations provide that a “taxpayer must capitalize amounts paid to a governmental agency to obtain, renew, renegotiate, or upgrade its rights under a trademark, trade name, copyright, license, permit, franchise, or other similar right granted by that governmental agency.” Taxpayers must also capitalize an amount paid to facilitate an acquisition or creation of an intangible.

Litigation expenses for patent suits may be deducted or must be capitalized depending on the nature of the litigation. Defense of title claims are treated as the acquisition or disposition of a capital asset and must be capitalized. In contrast, patent infringement claims arise in tort and can be deducted in the year the expense is incurred.

Applying these rules to Mylan’s legal expenses, the Tax Court held that expenses related to the preparation of the ANDA, including the certifications and notices, were capital expenses to acquire or create an intangible asset and had to be recovered incrementally over 15 years. However, the Tax Court held that the costs of defending against patent infringement suits is an ordinary and necessary business expense for a generic drug manufacturer and permitted Mylan to deduct its litigation expenses in the year the expense was incurred.
