Portfolio overview

Teknologian Tutkimuskeskus VTT Oy has been granted 247 US utility patents between 2015 and 2025, placing Teknologian Tutkimuskeskus VTT Oy at rank #1,670 across all assignees tracked by PlainPatent. This portfolio spans 155 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.5 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Teknologian Tutkimuskeskus VTT Oy is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Teknologian sits between J. Choo Limited (247 patents, rank #1,666) and University Of Cincinnati (246 patents, rank #1,674) - the closest US assignees by grant volume. The composite Innovation Score of 60.6/100 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 147 grants, compared with 100 in the 2015–2019 window, a +47% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Teknologian Tutkimuskeskus VTT Oy's 14.5 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 Teknologian Tutkimuskeskus VTT Oy 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.
