sounds reasonable , but i confused a little bit now .
as you know that back lock / linner lock and flipper etc. those good designs come from western world , how about Chinese use these designs ? are we intellectual theft?
how about people on other corners of the world who use this good design , and do you think those guys are intellectual theft ?
and do you think Einstein is a intellectual theft who stealing theory from isaac Newton ?
sorry about those Q , i am getting confused .
Dingy: Unless you're willing to spend the next page (at least) of hard to translate concepts, and go deep into history, patents, etc. know that this is a very long discussion.
The short version: there should be at least 15 years of protection of original ideas, uses, or designs, in some cases more. What is "fair" or not beyond that gets into uncertain territory: that of lawyers, philosophers, etc.
To answer your questions:
back lock- much older than 15 years, no patent applies.
liner lock- the
name "linerlock" was protected, not the actual lock. It also is a variation of a design over 100 years old.
flipper- most common designs were never protected; and there are many implementations NOT covered by patents.
are we intellectual theft?- Intellectual theft results when it goes against the law/patent. A BIG reason everyone seems so concerned is that the US constitution, which most Americans on this forum consider to be one of the most important documents ever written and live their lives based off it (in part) mentions patents. In essence, most Americans here believe it is part of what makes America America. The first patent law in the United States was passed 1 year after the constitution. Many of the founders of this country were inventors, and considered it a top priority.
how about people on other corners of the world who use this good design , and do you think those guys are intellectual theft ?
Use of design is fine AFTER a certain amount of time has expired. The idea is that while the creator is alive he should become RICH from a good idea.
and do you think Einstein is a intellectual theft who stealing theory from isaac Newton ?
Einstein- Born 1879.
Newton- Dead 1727
Enough time that Einstein was safe
