We’ve been the victim of our own success by inventing a technology that others want.

STAR EnviroTech, inventor of Diagnostic Smoke® Leak Detection Technology that is licensed to tool manufacturers supplying every major automaker and the aftermarket, has won the final of four patent challenges by competitor Redline Detection, according to a recent publication by the United States Patent and Trademark Office (USPTO). STAR won all four patent challenges, which were primarily over its methods of producing smoke vapor using inert gas, such as nitrogen, and embedding dye in smoke vapor. Sixteen additional STAR patents were unchallenged.

Winning all four USPTO reexaminations, a lengthy and thorough process, serves to definitively validate the three STAR patents challenged (their “nitrogen” patent was challenged twice). As is widely recognized, competitors often file USPTO challenges to sidetrack potential or pending patent infringement lawsuit by a patent owner.* It is STAR’s policy not to comment on potential or pending litigation.

“We were confident that the USPTO was going to rule in our favor in all four cases,” said STAR EnviroTech CEO Jim Saffie. “We’ve been the victim of our own success by inventing a technology that others want.”

STAR licenses its patented technology to many of the largest automotive tool and equipment manufacturers and distributors worldwide. STAR technology is recommended or required by virtually every major automaker, is available in 125 countries and is OEM-mandated in 41 countries. Its technology is inside 100% of OEM-approved smoke machines worldwide.

Based in Huntington Beach, California, STAR EnviroTech, a privately-held corporation, develops technology that is considered the “industry standard” for leak testing in fuel evaporative (EVAP), vacuum/induction and other vehicle systems. STAR licenses its technology to tool manufacturers and distributors worldwide, supplying the automotive, industrial, marine and aviation industries, including the Canadian Air Force and the U.S. Military.
