Wiley’s Patent Practice has built a 30-year record of obtaining successful outcomes for clients from a wide array of industries. We have considerable experience in representing both accused infringers and, in certain circumstances, patent holders in high-profile and high-stakes patent disputes. Our full-service Practice provides patent litigation, prosecution, and strategic counseling on IP licensing, due diligence, and portfolio development and valuation.

Our Practice garnered international attention following the historic settlement we secured for NTP, Inc., in a patent infringement case against the manufacturer of BlackBerry wireless devices. The settlement was one of the largest of its kind and resolved a fiercely contested case that, as noted by one media outlet, “captured the attention of Wall Street, the Supreme Court, and the governments of both Canada and the United States.”

Our Team

Widely recognized for their ability to handle complex patent matters, our attorneys draw on an uncommon combination of legal knowledge, technical expertise, and litigation skill to assist clients in achieving their business objectives related to patent law matters. Our team members boast extensive and diverse academic and professional backgrounds that enable them to represent clients in virtually all applicable fields of science and engineering. Particularly, we possess strong expertise in technology related to the Internet, satellite and wireless communications, computer software and hardware, consumer electronics, semiconductors, biotechnology, pharmaceuticals, and medical devices.

Wiley advises clients from a diverse range of high-tech industries, including biotechnology, pharmaceuticals, telecommunications, and consumer electronics. Both domestic and international clients have said that they choose Wiley for our ability as a Washington, DC law firm to uniquely combine our knowledge of the U.S. court system with the legal and political landscape. As a DC-based firm, our experience and capabilities in the U.S. Court of Appeals for the Federal Circuit, U.S. District Court for the Eastern District of Virginia, U.S. Court of Federal Claims, and Patent Trial and Appeal Board (PTAB) are top-notch. However, our practice is national, and we have extensive experience in every district court in the United States known for patent litigationincluding courts in Texas, Delaware, California, Florida, New York, and New Jersey.

Many of our attorneys clerked for judges in district courts or the Federal Circuit. All of our patent litigators hold engineering or science degrees, including many advanced degrees.

Our Approach

We are trial lawyers and counselors specializing in patent cases. Our approach is to prepare a case with the expectation that it will go to trial while also pursuing more efficient avenues to resolve the case, including strategic motions practice, the use of mediation or arbitration, and PTAB proceedings.

Our intensive preparation and dedication to staffing matters leanly and efficiently allows us to provide cost-effective representation to our clients. Unlike some of our highly leveraged peer firms, we staff cases with a small team of experienced attorneys who are fully immersed in the facts. With the full resources of our large firm behind us, we can increase staffing as needed, but the core team will handle the issues that we believe to be dispositive. This lean staffing model allows us to provide cost-effective representation to clients ranging from Fortune 500 corporations and segment-leading companies to startup and midcap venturesusually at overall rates that are far more competitive than those of our peer firms.

Licensing, Due Diligence and Intellectual Property Valuation

The firm assists clients in the licensing, sale, and purchase of patents and technology related thereto. Also, in connection with clients’ purchase of assets, the firm evaluates the intellectual property portfolio, including the validity of the patents being acquired, whether or not others are currently infringing the technology, and the clients’ vulnerability to others’ patented technology, and analyzes potential litigation outcomes.

Patent Trial and Appeal Board

The Patent Trial and Appeal Board (PTAB), formed in 2012 as a part of the America Invents Act, decides important issues of patentability. The PTAB provides several ways to contest patents, including inter partes reviews (IPRs), post-grant reviews (PGRs), covered business method reviews (CBMs) and derivation proceedings.

These proceedings give parties cost-effective methods of challenging an issued patent based on prior art patents and printed publications. These are intended to be a less expensive and faster option for post-grant patent challenges, with initial determinations within six months of filing and a final decision within 12 months.

Wiley attorneys and advisors work with clients on a comprehensive patent strategy that spans from inception to well beyond grant. Our attorneys have been deeply involved in the PTAB and previously the Board of Patent Appeals and Interferences (BPAI) and have assisted clients in numerous IPRs, PGRs, and CBMs, and have one of the best-known teams available to assist clients in future PTAB matters. 

Additionally, we have experience filing requests for ex parte reexamination. These proceedings can be a valuable strategic tool, allowing companies to challenge competitors patents with relative anonymity and without risk of estoppel that accompanies inter partes proceedings. Patent owners contemplating litigation or licensing may also use ex parte reexamination as a tool to refine claims and avoid prior art.   

IPR Experience

Since the introduction of IPRs in 2012, Wiley has assisted with more than 30 IPR proceedings, involving telecommunications hardware and software, semiconductors and microprocessors, and pharmaceutical formulations and compounds. Our experience includes advising clients on IPR strategies as part of our comprehensive, business-focused patent strategy.

Our representative IPR experience includes:

  • Assisted a major U.S. financial institution in preparing and filing IPR petitions related to data security patents used in connection with online banking.
  • Assisted a major U.S. corporation in preparing and filing IPR petitions related to wireless cell phone technologies.
  • Assisted our client in preparing and filing IPR petitions related to virtual memory for a processor.
  • Assisted our client and co-counsel in preparing and filing IPR petitions related to LED lighting technologies.

  • Assisted a major U.S. financial institution in preparing and filing CBM petitions related to data security patents used in connection with online banking.

International Trade Commission Section 337 Proceedings

Our attorneys are experienced in representing clients in patent infringement proceedings before the U.S. International Trade Commission (USITC) under Section 337 of the Tariff Act, which is designed to prevent the entry of infringing goods into the United States and to provide a resolution on an expedited scheduletypically within 12 months. We regularly serve clients in these specialized proceedings by successfully combining our expertise in international trade, intellectual property, and other fields, becoming especially active in bringing 337 actions against parties engaged in selling infringing pharmaceuticals over the Internet.
