The Intellectual Property Owners Association (IPO) reported today on data compiled by Esther Kepplinger, the Director of Patent Operations for Wilson Sonsini Goodrich & Rosati, which the IPO believes "has received little attention and has contributed to misunderstanding of patenting trends." In particular, Ms. Kepplinger's analysis shows that Requests for Continued Examination (RCEs) rose from 8.3% in 1998 to 19.6% in 2007, while continuation and divisional filings remained relatively stable over the same period (continuation filings rose from 10.7% to 11%; divisional filings dropped from 5.1% to 4.8%).
