Portfolio overview

Liaoning Upcera Co., Ltd. has been granted 5 US utility patents between 2020 and 2024, placing Liaoning Upcera Co., Ltd. at rank #48,435 across all assignees tracked by PlainPatent. This portfolio spans 12 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.8 claims per patent with primary concentration in F27D (DETAILS OR ACCESSORIES OF FURNACES, KILNS, OVENS OR RETORTS, IN SO FAR AS THEY ARE OF KINDS OCCURRING IN MORE THAN ONE KIND OF FURNACE). As a Foreign Corporation, Liaoning Upcera Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Liaoning sits between Levitate Technologies, Inc. (5 patents, rank #48,431) and Liberty Global Europe Holding B.v. (5 patents, rank #48,439) - the closest US assignees by grant volume. The composite Innovation Score of 36.1/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Filing cadence tells the strategic story. Historical data spans 2020 through 2024, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.

Claim depth and technology breadth together indicate competitive posture. Liaoning Upcera Co., Ltd.'s 12.8 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 12 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Liaoning Upcera Co., Ltd. against peers pursuing similar technology classes.

Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
