Portfolio overview

Contentguard Holdings, Inc. has been granted 10 US utility patents between 2016 and 2020, placing Contentguard Holdings, Inc. at rank #25,991 across all assignees tracked by PlainPatent. This portfolio spans 10 distinct Cooperative Patent Classification (CPC) subclasses, averaging 26.4 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a US Corporation, Contentguard Holdings, Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Contentguard sits between Comfort Office Furniture Co., Ltd Guangdong (10 patents, rank #25,987) and Corners, Co., Ltd. (10 patents, rank #25,995) - the closest US assignees by grant volume. The composite Innovation Score of 34.5/100 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. Between 2020 and 2025 the company received 1 grants, compared with 9 in the 2015–2019 window, a -89% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. Contentguard Holdings, Inc.'s 26.4 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 10 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Contentguard Holdings, Inc. 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.
