HIV test maker Inverness Medical Innovations has filed a lawsuit against rapid-HIV-test maker OraSure Technologies, alleging patent infringement in the manufacturing and selling of OraSure’s product, reports the Allentown, Pennsylvania, newspaper The Morning Call (, 4/18).

In 2002, OraSure’s well-known OraQuick test became the first rapid HIV test to be approved by the U.S. government. The test can detect HIV in both saliva and blood in less than 20 minutes.

The patent under debate involves OraQuick’s testing technology. According to The Morning Call, OraSure argues that it got the technology from pharmaceutical company Abbott Laboratories, and that it is not breaking any Inverness patents.

“[OraSure] believes that the asserted patent is invalid and intends to defend this lawsuit vigorously,” OraSure said in a press release.
