CHICAGO (TheStreet) -- Since the Supreme Court refused to narrow patents on software and business methods two years ago, there has been a patent market boom.

Just last month,

Analysts are now treating patents the way they do cows or acreage, offering per-patent estimates on bulk lots and looking forward to future sales of patent portfolios by the likes of

If the gold rush ends, however, credit

Richard Posner.

Posner, an esteemed conservative theorist is now a senior judge on the U.S. Court of Appeals in Chicago, and is currently sitting in as a trial judge.

But this is no ordinary patent trial. It's

v. Motorola. The unit of Motorola being sued is the one Google is buying.

Reporters are covering this one like it's a sports story. Among all the Android patent trials now going on around the world, this one may indeed be the Super Bowl. Apple alone has 30 lawyers on the case, charging Motorola with violating six key patents, while Motorola charges Apple with violating three of its own.

So far Posner has been going through motions. Most reporters will ignore the story until the trial, which is not expected to start until June. That would be a mistake, because the decisions a patent judge makes before trial, concerning what the trial will actually cover, can tell a lot about what the final result may be.

Posner has made many rulings already, but some trends now seem clear to me:

  • He takes no nonsense. Posner has ruled Apple's claim constructions "superior," those of Motorola "ridiculous."
  • You take risks when you bring broad patents to court. Posner has ruled one of Apple's patents invalid due to a lack of specificity.
  • Discovery is going to be expensive. Posner has told Google to hand Apple data covering its development of Android.
  • Only patents that are on point are going to be covered. Posner has identified one patent on "touchscreen heuristics" (Steve Jobs is listed as one of the inventors) as the centerpiece of the case.

The touch screen heuristics patent is Apple's ace. It would be very difficult for Android to invent its way around a basic patent on how one interacts with a touch screen.

Other courts may be taking note. A patent company called


has had its broad patent claims concerning the Web


in a Texas court. The case is Eolas Technologies Inc., v. Adobe Systems Inc. That same court, usually seen as especially friendly to patent holders, has also let Apple intervene in a case against another

, filed against its developers.

My own view is that what Posner has done so far to narrow the terms of debate, raise the cost of litigation, and demand clarity from litigants is drawing attention across the patent bar. This is without doubt a good thing.

Gradually, under Posner's leadership, the patent gold rush could now play out, with only the shiniest nuggets being judged valid and all parties being told that negotiating is a better way to handle commercial disputes than the warfare of trial. It won't end the patent debate, but it should encourage the biggest tech players to see that they'll make more profit doing business than fighting one another in court.

It may prove Posner's greatest contribution to the law yet.
