Portfolio overview

Murata Machinery, Ltd. has been granted 454 US utility patents between 2015 and 2025, placing Murata Machinery, Ltd. at rank #968 across all assignees tracked by PlainPatent. This portfolio spans 118 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.3 claims per patent with primary concentration in B65G (TRANSPORT OR STORAGE DEVICES, e.g. CONVEYORS FOR LOADING OR TIPPING, SHOP CONVEYOR SYSTEMS OR PNEUMATIC TUBE CONVEYORS). As a Foreign Corporation, Murata Machinery, Ltd. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Murata sits between Fisher Controls International Llc (456 patents, rank #964) and Toshiba Mitsubishi-electric Industrial Systems Corporation (452 patents, rank #972) - the closest US assignees by grant volume. The composite Innovation Score of 57.9/100 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 209 grants, compared with 245 in the 2015–2019 window, a -15% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Murata Machinery, Ltd.'s 9.3 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, 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 Murata Machinery, Ltd. 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.
