The verdict
Landmark holds 474 US patents across 42 technology areas, rank #937 of 50,000 tracked assignees.
Landmark Graphics Corporation has been granted 474 US utility patents between 2015 and 2025, placing Landmark Graphics Corporation at rank #937 across all assignees tracked by PlainPatent. This portfolio spans 42 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.2 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a US Corporation, Landmark Graphics Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Landmark sits between Caterpillar Paving Products Inc. (476 patents, rank #933) and Adeia Guides Inc. (470 patents, rank #941) - the closest US assignees by grant volume. The composite Innovation Score of 62.8/100 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. Between 2020 and 2025 the company received 254 grants, compared with 220 in the 2015–2019 window, a +15% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. The US 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. Landmark Graphics Corporation's 19.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 42 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Landmark Graphics Corporation against peers pursuing similar technology classes.

How to use this portfolio
Landmark's 474 grants land it in the top 2% 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.
