We routinely help clients protect and commercialize their intellectual property (IP) assets and provide due diligence on complex technology and IP transactions. We negotiate and draft IP licenses and transfers; provide strategic guidance on optimal structures for IP and IT transactions; and evaluate copyright, trademark, and patent portfolios and provide related due diligence activities in connection with IPOs, mergers and acquisitions, private equity investments, licenses, and other corporate transactions.
Practice Area
The United States International Trade Commission (ITC) is an increasingly popular venue for patent infringement litigation. More and more companies are seeking to halt importations of infringing products into the United States by turning to the ITC for expedited relief. Section 337 investigations conducted by the ITC provide complainants with a “fast track” to remedy IP matters that typically go to trial within 10 months. Since many Section 337 cases go to trial, selecting an ITC litigation team with a command of the technology, patent law, and specialized procedural practice is extremely important. We have handled more than 100 cases before the ITC.

What Is the Patent Trial and Appeal Board?
The Patent Trial and Appeal Board (PTAB) is a tribunal within U.S. Patent and Trademark Office. The PTAB oversees trial proceedings, namely: inter partes review (IPR), post-grant review (PGR), covered business method (CBM) review, and derivation proceedings. The Board also hears appeals from adverse patentability decisions by patent examiners in original applications, reissues, and reexaminations. And, while phasing out since the passage of the America Invents Act (AIA) in 2011, the PTAB is also responsible for deciding interferences. The PTAB was previously referred to as the Board of Patent Appeals and Interferences and was renamed by the AIA.
Law Glossary
Colloquially referred to as the “patent dance,” the BPCIA provides a framework that includes certain steps and a schedule during which the applicant and reference product sponsor exchange confidential information disclosed in the aBLA. During the patent dance, the applicant and sponsor identify the patents that could be litigated in the future during two potential phases of litigation. In the first phase, the sponsor can allege infringement of a subset of the patents identified during the patent dance. The second phase begins after the sponsor receives the Notice of Commercial Marketing from the applicant. During this second phase, the sponsor can assert any remaining patents that were not asserted in the first phase.

What Is Uniform Grant Guidance?
In 2014, the Federal Office of Management and Budget (OMB) issued Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards to Non-Federal Entities, commonly known as the Uniform Grant Guidance. The Uniform Grant Guidance is a government-wide, authoritative set of rules and requirements for federal awards intended to guard against the risk of waste, fraud, and abuse while reducing the administrative burden for non-federal entities receiving federal awards.
