TAKE AWAY: This case is particularly instructive for e-commerce websites. A typical e-commerce website invites customers to browse and then buy. Back in the dark ages, before the Internet, this kind of relationship often involved a written agreement that everyone had to sign. The equivalent for commerce over the Internet has developed over time. Now, you can post your contractual terms and conditions on your website. But, it looks like you need to go a couple of steps further to make it a binding contract. If you want to avoid B&N’s result, then you have to give your customer notice and an opportunity to accept the terms and conditions.

Can a hashtagged key word or phrase in a Tweet be registered as a trademark? For the uninitiated, Twitter is a social networking service where people communicate with each other with short messages (a “Tweet”). A Tweet can be tagged using a hashtag symbol (#) before a relevant keyword or phrase to categorize the Tweet and help it show up in a search. A business can generate buzz by using a hashtagged key word or phrase. For example #android and #SNL. There have been a couple of hashtag wars this year. One involved two taco restaurants over #tacotuesday. The owner of the hashtagged phrase tried to stop the other restaurant from using “Taco Tuesday” in an ad. The social media backlash caused the owner to back down. In another case, the Fraternity Collection brought suit against a competitor for using #fratcollection and #fraternitycollection. The court denied the competitor’s motion to dismiss the complaint deciding that the competitor’s use of the trademarks with the hashtagged phrases could cause customer confusion.

Before:Anyone who transferred data containing personal information from Europe to the U.S. was protected from liability for data breaches as long as they complied with Safe Harbor standards created by the European Commission. Thousands of companies "self-certified" themselves as having complied with the Safe Harbor standards. The Event: This month, the Court of Justice of the European Union issued its ruling in Schrems v. Data Protection Commissioner that the Safe Harbor is no longer available. The Court cited Edward Snowdon’s surveillance practices as proof that the Safe Harbor standards don’t protect European citizens. After: Anyone who transfers data containing personal information from Europe to the U.S. has to find new ways to protect themselves from liability for data breaches.
