In a recent case concerning the Patent Trial & Appeal Board’s application of the field of endeavor and reasonably pertinent tests for determining analogous art, the US Court of Appeals for the Federal Circuit provided valuable clarity
The Court ruled that the Board should not have required a petitioner to precisely articulate the relevant field of endeavor for the patent and prior art using the specific term, “field of endeavor”. This phrase, they noted, is not a magic phrase that needs to be employed for accurate test implementation.
Despite this, the Court did concur with the Board on one key issue. They agreed that the prior art was indeed not reasonably pertinent, due to its association with a distinctly different field of endeavor. This reaffirms previous precedents that prior art needs to be applicable and pertinent to the field it is being compared to.
This decision serves to further illuminate the intricacies of analogous art in patent law, and the importance of understanding how these aspects come into play during proceedings relating to patent disputes. While the precise wording used in articulating the relevant field of endeavor for a patent may not necessarily carry significant weight, the relevance and pertinence of prior art continues to hold substantial importance in these matters, as underscored by the Federal Circuit’s ruling.
