Overall rank by patents
#47,405
Across all tracked assignees
USPTO PatentsView assignee record - 5 granted patents across 2 technology areas, active 2020–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: B82Y (SPECIFIC USES OR APPLICATIONS OF NANOSTRUCTURES; MEASUREMENT OR ANALYSIS OF NANOSTRUCTURES; MANUFACTURE OR TREATMENT OF NANOSTRUCTURES).
The verdict
HT holds 5 US patents across 2 technology areas, rank #47,405 of 50,000 tracked assignees.
HT Materials Science (ip) Limited has been granted 5 US utility patents between 2020 and 2025, placing HT Materials Science (ip) Limited at rank #47,405 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 23.2 claims per patent with primary concentration in B82Y (SPECIFIC USES OR APPLICATIONS OF NANOSTRUCTURES; MEASUREMENT OR ANALYSIS OF NANOSTRUCTURES; MANUFACTURE OR TREATMENT OF NANOSTRUCTURES). As a Foreign Corporation, HT Materials Science (ip) Limited is one of the more focused assignees in the PatentsView dataset. By volume, HT sits between HS Foils OY (5 patents, rank #47,401) and Huang Chieh Metal Composite Material TECH. Co., Ltd. (5 patents, rank #47,409) - the closest US assignees by grant volume. The composite Innovation Score of 31.8/100 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 2025, 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. HT Materials Science (ip) Limited's 23.2 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark HT Materials Science (ip) Limited against peers pursuing similar technology classes.

How to use this portfolio
HT's 5 grants land it in the top 61% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
