Situation: Individual has successfully patented a cargo bar in 1991 (difference in his bar v. all others is the use of a hydraulic pump to apply pressure against a wall v. mechanical pressure - ratchet type mechanism).
The "field of invention" specifically states
"This invention relates to load bracing crossbars used to brace freight loads in compartments."
The 12 "claims" detail the parts and functions within the cargo bar and how they operate and interact with each other and apply pressure against a "wall" - no mention of trucking industry is mentioned in any of the claims - silent on industry but this is the only industry and application the inventor has used / sold his unit for the past 19 years.
Question: If someone takes the exact bar and does two things:
1) removes 2 pieces of existing tubing that determine the "operating range" for this specific bar from 83 inches to 109 inches (relevant range / size for trucks or trains), and installs 2 new longer pieces that increase the "operating range" to 144 inches (the operating range is not part of the claims), and,
2) Most importantly - takes the extended bar and uses it in a completely different industry and application which is not in the "field of invention" and where the inventor has only used his invention in the "trucking" industry, is this still an infringement?
Also, if it is "technically" still an infringement, is there any financial damage since the use in this completely different application and industry does not affect his revenue / income earned within the trucking industry? Finally, there is only one year left on his patent.
Thank you in advance for your consideration!
