I'm in the market for a programmable thermostat for my house. I had been considering several units, including yours and one from Nest Labs.
Apparently you've decided that it's more important to batter competitors with the legal system than actually, you know, put your supposed patents to use building a thermostat that your potential customers actually want to buy. You seem to be under the impression that suing other companies over patents on obvious ideas will make your own products look more attractive.
It's clear that you're out of touch with your market. I don't know what unit I'm going to buy for my house, but I can promise you that it won't be a Honeywell thermostat.
Putting aside the patent issue, if you and lots of other people send such emails, aren't you simply making it easier for Honeywell's lawyers to estimate damages owed?
Now you get to go out there and research every thermostat manufacturer to find out which ones aren't paying a licensing fee to Honeywell for these (and other) patents.
I think there's a very good chance that I've misunderstood your comment, but - for the sake of doubt - please tell me that you're not advocating fraud :)
Doesn't matter much, if they are still able to shut down a competitor like Nest legally, especially seeing as millions of people will continue to buy their products.
Better join some action to abolish the stupid patent laws.
I can't do anything about millions of people, but I can do something about my own buying patterns. I can also tell others why I did so and hope they agree with me.
