For the Urinary Incontinence Treatment Network: Retropubic versus Transobturator Midurethral Slings for Stress Incontinence Bladder control problems affects up to 50 percent of women, leading to substantial medical, interpersonal, and economic burdens.1,2 Among U.S. Women with urinary incontinence, 15 to 80 percent possess a component of stress incontinence,3 which results in leakage of urine during physical exertion, sneezing, and coughing.4 Of the women, 4 to 10 percent undergo surgery.5 In 1996, Ulmsten et al.6 introduced a procedure that involved the placement of a retropubic midurethral mesh sling for the treatment of stress incontinence; this process was less invasive than the Burch colposuspension and the autologous rectus fascial sling techniques which were the reference requirements at the time.In March 2007, the jury came back a verdict and only Affymetrix. The jury discovered that Illumina’s arrays, assays, scanners, software and related products infringed on one or more claims of most five of Affymetrix’ patents-in-match. The jury imposed a royalty of 15 %, and awarded total damages of more than $16.7 million for the period of 2002-2005. After the final judgment, the Court shall calculate the additional damages through the time of the ultimate judgment. The next phase of the trial, that may concentrate on the validity of Affymetrix ‘ patents, is planned to begin with on February 11, 2008. The next phase, likely to occur in May or June 2008, will determine whether Illumina’s infringement was willful.
