View Full Version : T9 Input for Searching Revisited

I read that someone had developed T9-type input (that's where you enter the
key corresponding to the letter only, like 262 for Bob and it figures out
what matches). There were concerns over patent infringements. The basic
concept of pressing numbers on a phone type pad to spell words is not
covered by the patent. The whole suggestion of words from a dictionary is
what I beleive it covered in the patent. My Rio Receiver uses T9 style input
to search for albums/songs/artists. If someone has or was thinking of
developing this for squeezebox, it would be great.

The problem is, that since it was talked about in here...the risk becomes ten
times greater if the patent owners wished to claim infringement. Its not really
so much about what you believe is covered, as being about how much you'd have to
pay to defend that belief in court. Having the patent mentioned in here, proves
foreknowledge. Thus, any penalty that might come up is magnified. This poses
too much risk, as it also provides larger motivation for a company to try and
claim infringement and cash in.

Basically, that discussion you refer back to made it rather clear that this
feature just wasn't going to be an option for the server.

ps. The Plugin API is quite extensive...not that it has anything to do with
what I have said above. Just a shameless plug ;)

I might add that the chances of the patent holder going after someone for
giving away a plug-in for a unheard of device (slim is a good product, but
certainly not mainstream) is close to zero. If they haven't gone after the
consumer electronics that use this type of input, and there are many that
don't use T9 but the number pressing, they aren't going after small potatoes.
Remember when you used to dial letters on the phone?????? You did't make
multiple key presses for each letter. This has been around forever.
