Portfolio overview

HKC Corporation Limited has been granted 1,232 US utility patents between 2019 and 2025, placing HKC Corporation Limited at rank #349 across all assignees tracked by PlainPatent. This portfolio spans 105 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.0 claims per patent with primary concentration in G09G (ARRANGEMENTS OR CIRCUITS FOR CONTROL OF INDICATING DEVICES USING STATIC MEANS TO PRESENT VARIABLE INFORMATION). As a Foreign Corporation, HKC Corporation Limited is one of the broader-portfolio assignees in the PatentsView dataset. By volume, HKC sits between Synopsys, Inc. (1,245 patents, rank #345) and Mahle International Gmbh (1,224 patents, rank #353) - the closest US assignees by grant volume. The composite Innovation Score of 67.7/100 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 1,176 grants, compared with 56 in the 2015–2019 window, a +2000% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. HKC Corporation Limited's 15.0 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HKC Corporation Limited against peers pursuing similar technology classes.

How to use this portfolio

HKC's 1,232 grants land it in the top 1% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - HKC ranks #349 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G09G - see who else leads that technology area. G09G leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
