Macslut, what you say is true, if Hypermac was manufacturing its own Magsafe connector.
But on their web site, they claim to be not violating Apple's patent, because they are not manufacturing the patented components, they are purchasing them from Apple (although they do not explain through which channel).
Which, in my knowledge, cannot be true.
Or, at least, Apple refused to sell the same components to my University, and we were told that Magsafe connectors can be lawfully purchased only buying a complete Magsafe power adaptor....
Now, I do not have insider's knowledge about the origin of the Magsafe components employed by Hypermac.
But only two cases are possible:
1) They really purchase them from Apple factories, through some sort of unauthorized backdoor. In this case their claim is true, but there is something illegal, or at least unauthorized, in the purchasing channel, which made Apple to react.
2) They actually manufacture the connector themselves, or by means of some subsidiary, in which case you are right, they are violating the Apple's patent. But, as I did explain, this would be just a minor, civil infringement, something which does not involve jail.
In this case, the severe penal crime is the false declaration on their web site. It depends on the country, but such a false statement is a major penal crime in most juridical environments. Here in Italy, for example, such a false statement is a crime which can cause up to 3 years in jail!
