I believe I saw on rennlist that he sold his patent to Jake Raby, which linked me to the aforementioned thread.

Read page 7. Post #126 actually has photos of his prototype. On Page 17 he says he can't talk about IMS anymore because he sold the patent. This was 2012. In 2013 LN introduced the "solution".



EDIT: My bad, somehow the prior link sent you to page 9 where he talks about a DOF to set of ball bearings instead of the bushing. He was working on several versions at the time, including a grease-fed bearing.

Use this link:

The IMS Soluion was developed by and installed in engines he built by Jake Raby prior to 2008, he developed it before he and Charles Navarro developed the ceramic hybrid. Jake also filed a “clean” patent application in July of 2012, meaning it does not reference any previous versions or prior patents that had been acquired. A search for a patent application for this other design produces no identifiable filings, so I have not idea if there was a patent; or if it exists or who it was sold to. Do you have a patent number for this other design?
