Provitro Biosciences Awarded First-Ever U.S. Patent for Large-Scale Production of Bamboo Plants

MT. VERNON, Wash., May 7, 2013 /PRNewswire/ -- Provitro Biosciences LLC (or "Provitro"), a subsidiary of Pendrell Corporation (NASDAQ: PCO) today received a patent from the United States Patent and Trademark Office covering foundational technologies that enable the rapid, disease-free, and high volume production of bamboo plants for the first time. The patent issued today reflects more than a decade of innovative research by Provitro in the field of non-genetically modified commercial-scale plant propagation methods.

Provitro was awarded U.S. Patent No. 8435789, "Media, Kits, Systems and Methods for the Micropropagation of Bamboo," which focuses on methods of propagating bamboo by including certain plant growth regulators in the medias used for initiating bamboo shoots from plant explants and then rapidly multiplying the number of shoots. This key innovation is the result of years of intensive research and development that for the first time enables the production of numerous, healthy bamboo plants for large-scale field plantings, including for the ornamental and timber bamboo industries.

"The technology developed by Provitro lays the foundation for serving vast global markets with a reliable, economical and environmentally beneficial source of alternative fiber that has previously not been available on a commercial scale," commented Jackie Heinricher, chief executive officer of Provitro Biosciences. "This patent reflects years of groundbreaking research efforts by the Provitro team, and underscores the potential we see in this technology."

In addition to this issued U.S. patent, Provitro Biosciences has a large, active intellectual property portfolio for the worldwide protection of its proprietary technologies. The company anticipates that this is just the first of many utility and Plant Patents to be issued for it's unique plant propagation methods and plant germplasms covering a wide variety of useful plant species in addition to bamboo.
