Patent Dispute Settled in Favor of Acufloor

Washington, DC, May 29, 2025-The U.S. Court of Appeals for the Federal Circuit reversed a district court decision of non-infringement in favor of Acufloor, a manufacturer of tile-leveling devices.

The new ruling in the company’s patent dispute with EvenTile and Forpac remands the case to the district court and now clears the path for Acufloor to pursue its patent infringement lawsuit against the two companies.

The case, Acufloor, LLC v. EvenTile, Inc., hinged on the district court’s interpretation of two key terms in Acufloor’s patents for tile-leveling devices. In its decision, the Federal Circuit fully adopted the company’s proposed definition of the "majority of an area" limitation, and it broadened the district court's construction of "edge." 

"Because the term ‘area’ in the limitation expressly refers to the area of tile-to-mortar-to-subfloor contact and not to the area of the base, the plain terms of the limitation support Acufloor’s construction,” Judge William Bryson wrote in the appellate decision.

The Federal Circuit’s reversal now allows Acufloor to present its case to a jury under a proper understanding and definition of its patent claims.
