Former PayPal employees Stephanie Tilenius and Osama Bedier, seen here at this week's Google Wallet launch, are at the center of a lawsuit alleging trade-secret theft.
NEW YORK (CNNMoney) -- PayPal and its parent company eBay sued Google this week. The company claims that two of its former top executives violated their contracts by sharing confidential information with Google and by negotiating with Google despite a clear conflict of interest.
California courts are famously unfriendly to employee non-compete agreements -- which means eBay will have a hard fight to prove its case. Here's a timeline of what eBay says happened, based on the details provided in its lawsuit.
March 12, 2001: Stephanie Tilenius joins eBay's staff and signs the company's non-disclosure agreement (NDA), agreeing not to solicit any eBay (EBAY, Fortune 500) employees for one year after leaving the company and not to disclose confidential eBay information.
Nov. 13, 2002: Osama Bedier begins work at PayPal and signs an NDA. He eventually becomes a vice president in charge of bringing mobile payment technology and services to retailers.

July 15, 2010: Tilenius begins attempting to lure Bedier away from PayPal to work for her at Google.

Nov. 19, 2010: Bedier asks Tilenius whether he could bring PayPal co-workers over to Google with him in an e-mail saying, "If folks want to join me on day one -- how possible is this?"
Nov. 27, 2010: Tilenius sends Bedier a text message saying "By next week there will be more information I can share and you will see how the role at Google could be expanded considerably." Page speaks with Bedier about expanding his proposed role at Google, and Bedier formally accepts the job offer.
Dec. 2, 2010: Bedier changes his mind about Google, and informs PayPal of his decision to remain at the company rather than accepting Google's offer.

Google issued a statement Friday saying it will fight the suit.
"Silicon Valley was built on the ability of individuals to use their knowledge and expertise to seek better employment opportunities, an idea recognized by both California law and public policy," a spokesman wrote in an e-mail to CNNMoney. "We respect trade secrets, and will defend ourselves against these claims."
