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.
