Portfolio overview

Hyosung TNC Corporation has been granted 6 US utility patents between 2019 and 2024, placing Hyosung TNC Corporation at rank #40,796 across all assignees tracked by PlainPatent. This portfolio spans 15 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.5 claims per patent with primary concentration in D01F (CHEMICAL FEATURES IN THE MANUFACTURE OF ARTIFICIAL FILAMENTS, THREADS, FIBRES, BRISTLES OR RIBBONS; APPARATUS SPECIALLY ADAPTED FOR THE MANUFACTURE OF CARBON FILAMENTS). As a Foreign Corporation, Hyosung TNC Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Hyosung sits between Hydril USA Manufacturing Llc (6 patents, rank #40,792) and Hyperspectral Corp. (6 patents, rank #40,800) - the closest US assignees by grant volume. The composite Innovation Score of 27.1/100 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. Between 2020 and 2025 the company received 4 grants, compared with 2 in the 2015–2019 window, a +100% 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. Hyosung TNC Corporation's 5.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 15 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Hyosung TNC Corporation 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.
