In a recent development, the Federal Circuit has chosen to vacate the Patent Trial and Appeal Board’s (PTAB) decision based on what they deemed to be an overly narrow claim construction. The matter in focus was Apple Inc. v. Corephotonics, LTD., a case that presented two key decisions to analyze.
The first issue at hand revolved around whether PTAB’s claim construction can be considered correct when intrinsic evidence suggests a different interpretation. As part of this, the Federal Circuit also questioned whether to vacate and remand PTAB’s first final written decision, which was grounded in its claim construction. The second aspect of review concerned whether in PTAB’s second final written decision, certain issues were properly addressed.
This recent event sparks a few key questions for legal professionals worldwide. It puts into focus the process by which PTAB interprets patent claim language, and has potential implications for the process of inter partes review, primarily questioning if it provides the ideal forum for resolving patent validity issues.
PTAB’s decisions deeply impact the landscape for corporations with strong intellectual property portfolios, as well as law firms having significant patent practices. This event reaffirms that legal professionals need to stay vigilant on how jurisprudence shifts in patent claim construction and how these shifts might affect the strategic management of technology companies’ patent portfolios.
