The best patent troll-killing bill yet.

The Innovation Act of 2013, introduced by House Judiciary Committee Chairman Rep. Bob Goodlatte (R-VA) and co-sponsored by a bipartisan coalition, offers a host of fixes to the problem of patent trolls—whose abusive litigation has exploded in recent years, putting a drain on our innovation economy and harming innocent end users.

The bill passed through the house with a bipartisan 325-91 vote. Now it's on to the Senate. Tell your senator to support the Innovation Act.

Patent trolls buy up patents and use them offensively against unsuspecting businesses—without creating or selling anything themselves. Making broad claims of infringement based on patents of questionable validity is the troll's favorite move. Most defendants choose to settle because patent litigation is risky and expensive—and trolls offer settlement amounts that, although still incredibly burdensome, are far cheaper than a lawsuit. Businesses who are targeted—including cafés running Wi-Fi, app developers, offices using scanners, and podcasters—lose both time and money, and innovation suffers.

Here's what the bill does:

Heightened Pleading: The bill requires patent holders to provide basic details (such as which patents and claims are at issue, as well as what products allegedly infringe and how) when it files a lawsuit.

Fee shifting: The bill allows for a court to require the loser in a patent case to pay the winning side's fees and costs. This makes it harder for trolls to use the extraordinary expense of patent litigation to force a settlement.

Transparency: The bill includes strong language requiring patent trolls to reveal the parties that would actually benefit from the litigation (called the real party in interest). Also, if the plaintiff is a shell-company patent troll, the defendant could require the real party in interest to join the litigation, forcing them to pay up if the patent troll can’t or won't pay.

Staying customer suits: The bill requires courts to stay patent litigation against customers (such as a café using an off-the-shelf router to provide Wi-Fi) when there is parallel litigation against the manufacturer.

Discovery reform: The bill shuts down expensive and often harassing discovery until the court has interpreted the patent, making it easier for defendants to dispose of frivolous cases early before the legal fees and court costs really add up.
