Abstract

Patent applications published June 1997 - November 1998 are reviewed to see how trends are evolving with time. Patents are divided into three subtypes: enabling chemistries, equipment and technologies, and therapeutic inventions using libraries. More than 170 patents reviewed testify to this explosive area. Nonetheless, many patents may require their claims amending before granting, and may also be very difficult to defend. Attention is drawn to articles from patent attorneys discussing the difficulties in prosecuting patents in this technology.
