Honolulu, HI, United States, 03/30/2006 - The race to patent anything related to nanotechnology continues to produce a flood of patents in the U.S., with the number of patents on average growing by over 30% every year since 2000..

Well over 5,000 nanotechnology-related patents have been issued in ther U.S. as of late March 2006.
The strongest growth can be observed in patents refering to "Nanoparticle" (147% CAGR since 2000), "Nanotube" (141%) and "Fullerene" (139%).
This trend clearly shows that nanotechnology firms and researchers are racing to secure patent protection for early-stage commercial applications but also might be trying to create license fee generating positions.
As patent offices are struggling with the soaring number of patent applications filed, nanotechnology- related patents create new challenges and problems.
One case in point is nanomedicine. According to Dr. Raj Bawa, author of a recent paper titled "Will the nanomedicine "patent land grab" thwart commercialization?" published online on Dec. 19, 2005 in Nanomedicine: Nanotechnology, Biology and Medicine, the critical role of patents to the nanomedicine "revolution" cannot be underestimated.
"When investors in nanomedicine or pharmaceutical companies consider the merits of a particular investment, patent issues are one of the most important items that they review" says Bawa. "There is also ample evidence that companies, start-ups, and universities are ascribing ever greater value and importance to patents."
"For a start-up company, patents are a means of validating the company’s foundational technology to attract investment" Bawa says. Universities are also becoming increasingly aggressive in patenting their nanotech-related research, with the hope of generating licensing revenue in the future.
In some areas, this situation has led to what is known as "patent thicket" – an overlapping set of patent rights requiring those seeking to commercialize new technology obtain licensees from multiple patentees. According to Bawa, such a classic patent thicket seems to be developing in the area of carbon nanotubes. The race for nanotech patents has not only produced overlapping patents, but has produced a flood of "unduly broad" nanopatents.
"Patent thickets are considered to discourage and stifle innovation" says Bawa. "Claims in such patent thickets have been characterized as often broad, overlapping and conflicting – a scenario ripe for massive patent litigation battles in the future."
According to Bawa, nanomedicine start-ups may soon find themselves in patent disputes with large, established companies, as well as between themselves. In most of the patent battles the larger entity with the deeper pockets will rule the day even if the innovators are on the other side.
"In the future the nanomedicine start-ups will become attractive acquisitions for larger companies, since takeover is generally a more cost effective alternative to litigation" says Bawa.
