Yeah, I'll drop this subject after a few facts I found, researching the U.S. Patents and Trademarks:
[And some corrections/additions like this!]
Pat. 4,892,272 (Hadzicki, 1990) describes the Revolution kite frame and two wing layout.
[Filed on Oct. 14, 1988, the patent would normally expire on Oct. 14 2008!]
Pat. numerous (Hadzicki et al) describe the manufacturing machines for the spars etc.
Pat. 4,286,762 (Prouty) describes a dual line kite design. I got too tired to read it, but it probably is the Rogallo type everyone makes.
Pat. 5,213,289 (Barresi) - Hmm, David B., not John B.
[Just for grins and chuckles]
Unfortunately, I cannot remember how to get the illustrations. Reading the verbal descriptions is time consuming and ambiguous.
[You have to download one of two programs the Patent office recommends to decode the special TIFF format.]
Well, it should be clear there is a patent covering the basic design.
[Sorry, my mistake - probably no patent anymore.]
"Revolution" is a registered trademark,
and graphic designs almost certainly are covered by copyright.
The panel layouts are probably also covered by copyright - that is not clear to me.
"Rev" is apparently not trademarked. One could argue that it infringes on "Revolution" by similarity, since the intent is obvious.
How that information will help the pirates is beyond me. I never much liked the notion of security through ignorance.
[The information is publicly available to them, only us be ignorant.]
[Actually, patent expiration is intentional, to encourage commerce through competition.]
It seems to me that all the eBay auctions with Revolution-like kites, with panel layouts obviously copied or with unique sail graphics, are all questionable.
Obviously, I am no lawyer, so the legal questions are beyond me. That should be the job of Revolution to pursue. Often legal remedies are too expensive to pursue, though.
Is anyone questioning eBay?
[Assuming no patent protection, there appears to be only one seller offering questionable auctions today - including non-Revolution "Rev 1.5 SLE" and "Rev Blast" kites. Not a direct trademark infringement (?), but intent to deceive is obvious.]
Over and OUT [again]
