Its tech biz, first come, first serv... Besides i u r generalizing the patent then that's not how it works. The problem is over 50% of the patent is copied and key features and designs are implemented into the htc phones. These days if u come up with a new idea u patent it. In this case apple did since it was first. I remember clearly watching a movie regarding windscreen wipers and that design was patented. You can't deny intellectual property belongs to someone who serves the patent first.
That patent is very detailed from a technology design perspective and the difficulty is in achieving every step with technology without copying the other.
Patents can be sold and bought. That is the sad reality but it offers companies who create technologies then go bankrupt to reap the benefits through sales and licensing from the new owner. This way intellectual properties drive the force to innovate and make a buck from just the idea. Patents is a product that companies produce , license, sell and demand retribution for being infringed. Its a source of income.
Specialist are dragged from the industries by the law to investigate and tear down HTC and apple phones to the bone and conclude upon what they see. Officially apple filed that 10 patents were infringed. HTC only infringed 2 as was concluded by the techys report and judge.
If samsung was asked to design a product without the patent it could not do it without copying apple. Period. E.g the Magic mouse: Anyone who puts a multi-touch on a mouse is gona get sued for just the design. Don't matter if the multi-touch uses different tech from apple.
