Inter Partes Review

Weil’s pioneering leadership is what many of the world’s premier companies rely on when navigating the ever-changing patent landscape. Our experience guiding clients through the emerging Patent Office procedure for evaluating the validity of issued patents, known as Inter Partes Review (IPR), is no exception to our leadership in the intellectual property arena.

Experts in the Field

Most of our litigators have science or technology degrees and are registered to practice before the Patent Office. This combination of deep litigation experience and Patent Office know-how gives our clients a strategic advantage in these high-stakes proceedings before the Patent Trial and Appeal Board (PTAB).

Our lawyers are also well-versed thought leaders in IPRs and deeply knowledgeable about their myriad implications – their utility, risks and costs – especially when considered in the context of co-pending patent litigation. Weil has managed multiple IPR and CBMR proceedings and is currently counseling numerous companies, across a broad spectrum of technologies, including those in the biopharma space, on anticipated IPR proceedings. In many instances we are handling both the IPR or CBMR proceedings as well as co-pending litigation for our clients, enabling us to bring efficiencies and an existing deep knowledge of the relevant technology to the PTAB proceedings.
