Unfortunately, this is in licensing infringement with the actual Helveticards (helveticards.ryanmyers.me). I have contacted the creator and informed him of the conflict.
Second, the word "Helvetica" is trademarked in reference to a font or a software program relating to fonts. So unless he plans on selling a font called Helvetica, he can write the word as much as he pleases. It's the Latin name for Switzerland.
Third, until you trademark the term Helveticards and he starts offering a product in a similar likeness, this discussion is between him and Linotype. Stop trying to peddle your own product. Too bad, because I actually like your cards!
While you aren't completely correct in your second point (as I found out in my own dealings with LinoType), I do want to take a moment to apologize. I'm sorry for barging in a causing raucous that could have easily been handled privately.
To all, please accept my apology for lack of tact. You live, you learn, you do better next time.
Regards, Ryan Myers
Seriously, there's more than a lack of tact there.
Happy to change the name though, this was just a quick, weekend hack about two years ago.
I'm sure you're a nice enough guy in the real world, but you certainly came off badly here.
This is CSS demo that was purely meant to be a learning/teaching exercise. There is absolutely no competition.
But how about rather than complaining that someone else 'took your name', though yours is obviously equally inspired from LinoType you work on building a better business?
I know I personally bought your cards a few years ago and still have yet to receive them despite emails/Tweets and the like.
You're doing yourself absolutely no favours with behaviour like this. This sort of behaviour only works with giant companies, and still then it often creates bad blood for the consumer.
Regarding your purchase, based on my records, your cards were shipped on Nov 22, 2011.
And as the 4 emails and one tweet I have sent you over the years, I never received them.
