This is wrong. The license says:
>3. Grant of Patent License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by such Contributor that are necessarily infringed by their Contribution(s) alone or by combination of their Contribution(s) with the Work to which such Contribution(s) was submitted.
'Each Contributor heareby grants to you, ... licence ... to use ... the Work ....'
However, I am very much not a lawyer. Like Chris, I do talk to IP lawyers as part of my work.
Also, has anybody noticed that every single language in existence borrows features from some other language FOR FREE? If all languages started patenting their features then we soon will be completely boggled with lawsuits or unable to invent new, better languages as they will not be able to use already established convenient features.
There are only this many simple convenient ways to denote programming language features. There is limited number of single character operators and ways you can organize them. Granting patents to single characters is just stupid.
