A Woburn company says a patent granted to Hopkinton-based Caliper Life Sciences yesterday is invalid, and has filed a re-examination request asking the U.S. Patent and Trademark Office to revoke the patent.
VisEn Medical Inc. of Woburn says the patent covers basic methods of in vivo imaging that were already “fundamentally understood in the industry,” and were “well known and in use” before the patent was applied for.
VisEn develops and commercializes fluorescence in vivo imaging technology, and was founded in 2000 by academic medical researchers.
In vivo imaging allows non-invasive insight into living organisms, and helps to understand metabolic processes and diseases related to changes in the body.
