SAN FRANCISCO (AP) — A discrimination lawsuit that put a spotlight on gender balance and working conditions for women at Silicon Valley firms ended with a jury rejecting the female plaintiff's claims. The jury of six men and six women determined Friday venture capital firm Kleiner Perkins Caufield & Byers did not discriminate against Ellen Pao because she was a women and did not retaliate against her by failing to promote her and firing her after she filed a sex discrimination complaint. In making their case during the five-week trial, Pao's attorneys said she was excluded from an all-male dinner at the home of Vice President Al Gore; received a book of erotic poetry from a partner; was asked to take notes like a secretary at a meeting; and subjected to talk about pornography aboard a private plane. During her testimony, Pao told jurors that her lawsuit was intended in part to create equal opportunities for women in the venture capital sector.
