Patent Litigation
Our litigators have successfully asserted and defended patent cases in federal courts throughout the country, including jurisdictions with heavy patent dockets (e.g., California, Delaware, Massachusetts, New Jersey, Pennsylvania, Texas, and Virginia), the Court of Appeals for the Federal Circuit, and before the International Trade Commission. Foremost, we are trial lawyers, and our diverse IP litigation practice enables us to excel across a wide range of technologies. Our approach is to pair lawyers who have strong technical backgrounds in the relevant technology with experienced trial lawyers, thereby giving our clients the best of both worlds: a litigation and trial team which can construct the strongest possible technical arguments in support of our position and can also explain our case to a judge and jury in language which is simple and persuasive.
From individual inventors to Fortune 500 companies, our lawyers have represented a wide range of clients in patent matters and have successfully litigated against some of the largest law firms in the U.S. The firm’s patent practice has been recognized in the Chambers USA guide, and the firm has been ranked as a recommended firm for patent litigation by Managing Intellectual Property magazine’s IP Stars guide. Patent Litigation group members have also been recognized individually by Chambers, as IP stars by Managing Intellectual Property, and as part of IAM’s Patent 1000 list.
Our patent attorneys are also skillful and experienced negotiators, able to assist our clients in maximizing the value of an IP asset sale. We draft infringement and validity opinions, conduct detailed intellectual property due diligence and freedom-to-operate analyses, and counsel clients on monetizing strategies for patent portfolios.

The U.S. Supreme Court recently ruled that users of generic drugs cannot bring state-law design defect claims against generics makers because the manufacturers cannot change a drug's design under federal law. Walia notes, "The decision reaffirms the fundamental principle of the Hatch-Waxman Act: Generic manufacturers must follow FDA requirements for pharmaceutical compositions and labels. A manufacturer of generic drugs cannot change a generic drug's design or labeling under federal law, and therefore should not be penalized for following federal law."

The past few months have shed some light on the Patent Trial and Appeal Board’s approach to estoppel in post-grant proceedings, which applies to final written decisions on a claim-by-claim basis. Moreover, estoppel applies not only when a petitioner, or a real party in interest or privy of the petitioner, raised the arguments in a prior IPR or PGR proceeding, but also when he/she “reasonably could have raised” them.
In this article, Dr. Walia suggests that the Federal Circuit appears to be leaning toword a more flexible approach in terms of pharmaceutical patens, as evidenced in recent decisions.
Obviousness type double patenting (ODP), or non-statutory double patenting, is a judicially created doctrine meant to prevent a party from extending an earlier commonly owned patent’s term by claiming patentably indistinct subject matter through claims in a later patent. An ODP rejection of the second patent application with indistinct patentable claims can be overcome by filing a terminal disclaimer as long as both patents are commonly owned or a joint research agreement exists for both patents.
Inter Partes Review (IPR) is conducted at the Patent Trial and Appeal Board (PTAB) to review the patentability of claims only on the basis of anticipation and obviousness based only on patents or printed publications. So far, more than 70 percent of petitions have resulted in instituting of an IPR. This article discusses best practices for petitioning for an IPR and how it can be a very attractive route for potentially invalidating patent claims for generics which do not have the 180-day market exclusivity incentive
In Actavis, the Supreme Court declined to hold these agreements presumptively anticompetitive as advocated by the FTC or apply the scope-of-the-patent test, but held that such agreements should be reviewed by the rule-of-reason antitrust standard. This article discusses the implications of this decision.
In Hatch-Waxman litigation, the filing of an ANDA seeking approval to market a pharmaceutical product before the expiration of patents covering that product is a technical act of infringement sufficient to establish jurisdiction to resolve the issues of patent infringement and validity in litigation. This article examines the litigation that follows the ANDA filing by considering whether the product that is likely to be sold would infringe the patent.
In affirming the district court’s award of attorneys’ fees, the Federal Circuit agreed with the district court that the patent holder’s failure to “produce admissible evidence of infringement” rendered the case exceptional, historically a very high bar for prevailing defendants to meet. However, in reaching this decision, the Federal Circuit relied upon two recent U.S. Supreme Court decisions, Octane Fitness, LLC v. ICON Health & Fitness, Inc. and Highmark, Inc. v. Allcare Health Mgmt. Sys., Inc., both of which significantly relaxed the standard for what is deemed an “exceptional case” under § 285.
The article provides an analysis of recent remarks by Assistant Attorney General Stuart Delery, in which the AAG described the government’s approach to enforcement actions targeting off-label promotion of drugs and devices. Considering the AAG’s remarks along with recent FDA draft guidance on the distribution of scientific literature, the article focuses on the effect that First Amendment concerns, intensified by recent case law developments, may have had on the way in which the government investigates cases, evaluates evidence, and develops and presents its theories of liability in off-label cases.
A patent on cloning human stem cells was issued recently by the U.S. Patent Office to a disgraced scientist who had admitted to fabricating his results. Despite appearances, however, the issuance of this patent is not a glaring mistake on the part of the USPTO, nor is it certain that the patent was obtained by fraud or should be held invalid. As long as the inventor was scrupulously honest in his dealings with the USPTO, he may be entitled to the monopoly rights granted to him.
