Short Summary
Fluidmaster successfully moved forward with its IPR challenge against Danco's patent (9103105) regarding toilet fill valves. The Board granted institution on multiple grounds, setting the stage for a full trial to determine if the claims are unpatentable over prior art combinations.
Detailed Summary
In this Institution Decision, Fluidmaster, Inc., petitioner, successfully challenged Danco, Inc.'s patent (9103105) covering toilet fill valves. The Board granted institution on multiple grounds of obviousness (§ 103) and novelty (§ 102). A key aspect of the decision involved claim construction, where 'integrally molded with' was construed narrowly as meaning molded together as a single structure. This ruling allows Fluidmaster to proceed to trial, asserting that the claimed features are anticipated or rendered obvious by prior art combinations like Guoxin/Ho and Brown/Ho.
