Mylan Inc v. Commissioner of Internal Revenue, No. 22-1193 (3d Cir. 2023)
Annotate this Case
Mylan regularly submitted abbreviated new drug applications (ANDAs) to the FDA, often including Paragraph IV certifications stating that the proposed generic drug at issue would not infringe valid patents. Mylan incurred tens of millions of dollars in legal fees defending itself in about 120 patent infringement suits, 35 U.S.C. 271(e)(2). Mylan incurred additional, much lower legal fees in preparing the notice letters associated with the Paragraph IV certifications. Mylan's fees were $46,158,403, $38,211,911, and $38,618,993 during 2012, 2013, and 2014, respectively, for preparing notice letters and litigating the ANDA suits. In tax filings, Mylan deducted those amounts in the years incurred. The IRS responded that Mylan could not deduct the nearly $130 million of legal expenses incurred from 2012-2014 and that its additional tax liability was about $50 million.
The Tax Court considered expert testimony regarding internal FDA processes and the typical course of dealing between an ANDA applicant and the FDA during the submission process for an ANDA with a paragraph IV certification and held that the legal expenses Mylan incurred to prepare notice letters were required to be capitalized because they were necessary to obtain FDA approval of its generic drugs. The Third Circuit affirmed its holding that the legal expenses incurred to defend patent infringement suits were deductible as ordinary and necessary business expenses because the patent litigation was distinct from the FDA approval process.
