The "Defensive Patent License" an Open Defensive Patent Pool

capedgirardeau writes "Via Cory Doctorow at BoingBoing:: 'Ars Technica's Jon Brodkin has an in-depth look at the "Defensive Patent License," a kind of judo for the patent system created by ... EFF's Jason Schultz (who started EFF's Patent Busting Project) and ... Jen Urban (who co-created the ChillingEffects clearinghouse). As you'd expect from two such killer legal freedom fighters, the DPL is audacious, exciting, and wicked cool. It's a license pool that companies opt into, and members of the pool pledge not to sue one another for infringement. If you're ever being sued for patent infringement, you can get an automatic license to a conflicting patent just by throwing your patents into the pool. The more patent trolls threaten people, the more incentive there is to join the league of Internet patent freedom fighters."

worthless against trolls

[sribe]

This would provide, potentially, fine defense against being sued by an actual company with actual products, because with a large patent pool you'd be likely to find one that your attacker is potentially infringing.

But patent trolls do not infringe, because they do not have products.

I'm a patent attorney and I agree.

Unless I'm fundamentally misunderstanding the purpose, there's no legal judo here. It can't protect you against non-participants. It certainly can't protect you against trolls. It only seems to protect you against people/entities already inclined not to use their patents aggressively.

What would be more useful is if it worked this way (it doesn't):

Non-participating entity A sues participating entity B.
Entity B has no useful patents with which to sue Entity A.
Some other participating Entity C does have a useful patent to sue Entity A.
Entity B can use Entity C's patents against Entity A.

But, this scheme doesn't make that happen. In fact, there's basically no way to make Entity C actually use its patents against Entity A on behalf of Entity B. Neither the patent law nor this license could make Entity C's patents a weapon against A.

Even if there were a way, no one with any patents of value would sign up for the DPL since: (1) the cost of enforcing the patent is going to be expensive; (2) turning over the right to enforce the patent to Entity B would be like handing the keys to your car to someone you don't know and assuming responsibility for any damage to your car (e.g., patent is held invalid, found not infringed, etc.); and (3) a priori knowledge of the value of the patent might mean that you'd be in a better defensive position not having granted "free" licenses to every participant (something that inevitably will come up in a damage calculation).

  The DPL is a solution searching for a problem. And a foolish solution at that.

A company called RPX has created a much "better" solution for those that can afford to be part of the membership. Of course, in that case, RPX is the point person and has an ability to make things happen and has their own patents that they've acquired.

This is the least of it. This license seems to me quite dangerous. Actual patent infringment is unlikely to take place in patent creating entities in future. Imagine Microsoft split into "Microsoft Enforcers" (hoards patents, makes patent trolls) "Microsoft Software" (sells software ordered from Microsoft Developers, buy's "covenant's not to sue" from Microsoft Enforcers) "Microsoft Developers" (sells software/people to Microsoft Software; sells patents to Microsoft Enforcers) "Microsoft Troll(n)" (loans patents from Microsoft Enforcers, makes lawsuits - one troll per patent;).

N.B. I have probably got some of the details wrong, and you may have to use a company registration for Microsoft in a non-software patents jurisdiction to transfer the software from Microsoft Developers to Microsoft Software but you get the idea.

• Microsoft Software does all the infringement; it could even potentially join the DPL. It never sues anyone so the DPL causes it no problems.
• Microsoft Enforcers never does any software; both it and the Microsoft Trolls that it spins off cannot be sued for infringement since they never do.

The only defence against this is that, if Microsoft Troll(527) sues you, you have to sue Microsoft Software back. The DPL and other similar patent pools can endanger that.

Basically, if you don't reserve the right to sue any apparently "innocent" entity which has taken a patent license or even taken advantage of a "covenant not to sue" then you may not be able to use patents defensively. It's probably an absolute requirement that you be able to sue Microsoft's customers for things that Microsoft related entities do. Anything else will leave you vulnerable to a troll suit that, even if you manage to settle, allows your competitor to force you out of the market by charging you per system you deliver.

Re:patent holders only?

PLEASE Patent a method for doing this! I would pay CASH MONEY to be able to PHYSICALLY shit on Apple and Microsoft over the internet! There are MILLIONS to be made here, man! MILLIONS!

Woah, hold up there. I'm not coming up with the method, I'm talking about patenting the idea. Let someone else figure out a method and then sue them.

That is how these things work right?
