Delivering Wins for Patent Challengers
Our practitioners have extensive experience securing significant wins for various petitioners in invalidating patents. Our deep understanding of the technology allows us to identify prior art where others cannot, often relying not only on patents, but other specialized publications, such as doctoral theses, scientific publications, standard essential publications, and complex textbooks. And our extensive familiarity with the PTAB's complex procedural rules allows us to deliver significant wins for our clients.
For example, Desmarais LLP helped secure numerous wins for one of the world's largest semiconductor manufacturing company by not only finding key pieces of prior art that other firms were not able to find, but also finding lack of written description arguments that allowed the use of Patent Owner's own earlier publication as prior art. As another example, Desmarais LLP attorneys were successful in demonstrating unpatentability of proposed substitute claims through a motion to amend initiated by the Patent Owner. Besides inter partes review proceedings, Desmarais LLP attorneys are also experienced practicing at the USPTO in other proceedings. For example, Desmarais LLP routinely employs ex parte re-examination proceedings, leading to numerous findings of substantial new questions of patentability and subsequent cancellation or amendment of the claims.
Delivering Wins for Patent Owners
Desmarais LLP attorneys also have broad experience securing wins for patent owners. Our practitioners' deep understanding of the technology allows us to identify deficiencies in validity challenges in inter partes review and ex parte reexamination proceedings on behalf of patent owner. Desmarais LLP attorneys have successfully defended patents by highlighting both substantive as well as procedural deficiencies and preventing the institution of a trial before the Board.
For example, our practitioners prevented institution of IPR proceedings by highlighting Petitioner's failure to demonstrate certain limitations were taught by the prior art. We also successfully highlighted Petitioner's failure to demonstrate public availability of the publication to prevent institution. Our practitioners have also secured discretionary denials of IPR institution based on parallel litigation schedules and by highlighting that it would not be an efficient use of the Board's resources when 80% of the challenged Grounds did not demonstrate a reasonable likelihood of success. In cases that have proceeded to trial before the Board, we have successfully defended the patentability of the challenged claims, ultimately preserving jury verdicts and delivering wins in final written decisions.
