I am developing an app for iOS devices which has almost the same guided view type reader for comic panels. There are a lot of posts on the web about fights between Marvel and Comixology regarding the patent of this viewer. I was wondering if my reader app can violate the patent guidelines. Secondly, if it does, still in wiki the technology has been written as "patent-pending"and if I can publish my app right now, will It still be an offensive app?
Systems, Methods, and Media for Presenting Panel-Based Electronic Documents US 20100318895 is an application, not yet an issued patent. Some of the web articles that mention it also note that Marvel (via Disney) has an issued patent US 8301999 that covers similar territory.
The entire history of the prosecution of any recent patent or application can be seen at USPTO Public PAIR. The current status of the Comixology application seen there is:
It has had a long history now of many rejections and corresponding claim amendments and arguments. Anyone can follow the progress there. Unless and until a patent is granted its owner has no right to stop anyone. Of course, once issued, the fact that something is already shipping isn't relevant to whether or not it infringes.
