Portfolio overview

LOUISIANA TECH RESEARCH CORPORATION has been granted 25 US utility patents between 2015 and 2024, placing LOUISIANA TECH RESEARCH CORPORATION at rank #12,093 across all assignees tracked by PlainPatent. This portfolio spans 49 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.1 claims per patent with primary concentration in C04B (LIME, MAGNESIA; SLAG; CEMENTS; COMPOSITIONS THEREOF, e.g. MORTARS, CONCRETE OR LIKE BUILDING MATERIALS; ARTIFICIAL STONE ; CERAMICS ; REFRACTORIES; TREATMENT OF NATURAL STONE). As a US Corporation, LOUISIANA TECH RESEARCH CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 48.3/100 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 8 grants, compared with 17 in the 2015–2019 window, a -53% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. LOUISIANA TECH RESEARCH CORPORATION's 17.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 49 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark LOUISIANA TECH RESEARCH CORPORATION against peers pursuing similar technology classes.

How to use this portfolio

Louisiana's 25 grants land it in the top 17% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Louisiana ranks #12,093 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in C04B - see who else leads that technology area. C04B leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
