Title: I created a transit app for the TTC in Toronto.
(https://itunes.apple.com/ca/app/ttc-watch-for-toronto/id505286932?mt=8)<p>Yesterday, I received a package from Lemer &#38; Company representing Dovden Investments, Ltd. The package claims that my app infriges their patents.<p>Patents:<p>http://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/2283239/summary.html<p>http://brevets-patents.ic.gc.ca/opic-cipo/cpd/eng/patent/2363556/summary.html<p>I am reaching out to HN because I know there are many transit apps out there that have the same functionality: letting users know when the next bus will arrive using a third-party API (from NextBus, or GTFS Realtime for example).<p>So, if anyone has dealt with Dovden or has had a similar experience (or ArrivalStar in the US), please contact me at barum.rho@gmail.com<p>More details:
My apps use the API provided by NextBus who apparently licensed these patents. The patents describe a system that includes a vehicle unit (GPS) and a central server that processes GPS locations, neither of which are part of my app. They offered a "discounted" licensing fee, but my apps have generated income nowhere near the amount.<p>Please upvote for a better chance of finding other transit app developers.
