Regarding 3rd party In-App purchases for apple iOS apps, I would consider whether the patent covers Apple's iOS framework for In-App purchases through the App Store. It would behoove Apple to apply for a patent this software process, in order to prevent a third party from patenting the process / technology and leeching money from Apple's App store commerce, whether LodeSys's patent applies here is controversial. There are rumors that the Justice department is investigating LodeSys's actions on the basis of whether they violate RICO laws, and we will have wait and see, whether Justice takes any action in the future.
I would remind people that the Patent office issuing a patent for some collection of claims, does not mean that patent can't be overturned in court.
Also, I would remind Open Source Software programmers, that IP law with software patents and trademarks will always pose barriers and hurdles to take in mind. As the software market matures, the software industry is beginning to resemble the pharmaceutical industry, where brand-name drugs have a legal monopoly for the that country for the remaining life of the patent, after which generic drugs can be introduced in a regulated fashion. Until the Intellectual property law principles of software patents are restricted or clarified, the company with the biggest legal staff has the bigger stick.
One would support furthers efforts by the EFF, ACM and other independent groups to support efforts like the ACLU to help the little guy / company toe the IP law line, and survive.
