Indeed, and this increased risk would make it an even greater imperative for potential victims to form or support a patent-busting cooperative as suggested by several commenters already - much like how some prey animals form defensive herds against hunting packs. Hopefully cases like these will push companies to band together and not remain tight-lipped like they were on the Soverain case (until Newegg broke the chain).
There's a coalition for the open Internet, why not a coalition for fair innovation in technology? (Perhaps in collaboration with the EFF's Defend Innovation initiative?)[1]

edit: Interesting trivia from a legal news site:

In Tuesday's decision, the Federal Circuit ruled that three of Soverain's core patents are invalid on obviousness grounds. "The district court's conclusion that a prima facie case of obviousness was not met is not explained by the court by Soverain, and does not accord with the record," the appellate panel ruled. "[T]he trial record contains extensive testimony of the experts for both sides, discussing every claimed element of the patented subject matter and the prior art system."
If I understand this right, Judge Davis simply ignored all Newegg's testimony about prior art and ruled that they hadn't even made a prima facie case for obviousness. Thankfully the Court of Appeals didn't think so. I wonder if Davis was simply leaving the issue of patent validity to a higher court to decide, or if he really had a good legal reason to ignore prior art and the evidence for obviousness. The Soverain lawyer's blogpost provides an inside view on the 2010 case: http://mcsmith.blogs.com/eastern_district_of_texas/2010/08/j...
In the end the jury's $2.5m award might not even have covered Soverain's legal costs, meaning that it wasn't a win for them either - more of a draw.
Reading the fresh Appeals opinion is interesting too: http://www.cafc.uscourts.gov/images/stories/opinions-orders/...
Precedent
agrees with Newegg that a person of ordinary skill[2] could
have adapted the CompuServe order command to known
browser capabilities when these capabilities became
commonplace, and that it was obvious to do so. The
product identifier message term does not distinguish the
shopping cart claims from the prior art CompuServe Mall.
Clearly sensible reasoning, not misled by technicalities and sophistry - I like it. The opinion is basically a no-nonsense slap-down of Soverain's arguments and Davis's ruling, which will no doubt restore your confidence in the justice system a little. It was surprisingly easy for a layman like me to read, too.
