    Next time you whip up a linked list, just be sure you aren't infringing on any patents[^].

      Bogus, man.  In my CS class in 1981 I had to build a linked list using arrays.  What'll they patent next?  Recursion?  (I had to simulate recursion using my own call stack in the same course.) :| Now rounded rectangles... that's a different matter altogether. /ravi

          Aaah, reminds me of one of my worst CS exam questions: Traverse a binary tree without using recursion. Not Earth shattering, but unexpected and quite hard in the last minutes of a three hour exam.

            It was a great course!  I think we lost about half the students.  It was the first required course in the MS(CS) program, meant to determine if you were qualified to continue in the program. /ravi

              :omg: What on earth possessed the patent office, in 2006, to grant that? There is 30 years of prior art, and it's not even obscure!

                    they patented the Multiply_linked_list[^]? :(( Wiki:

                    In a multiply linked list, each node contains two or more link fields, each field being used to connect the same set of data records in a different order (e.g., by name, by department, by date of birth, etc.). (While doubly linked lists can be seen as special cases of multiply linked list, the fact that the two orders are opposite to each other leads to simpler and more efficient algorithms, so they are usually treated as a separate case.)

                            Like Generic Medicine which gets manufactured at very cheaper cost, does the Patent expiry to hold for software code/design/concept etc?

                              Well, someone did file a patent request for the wheelbarrow, back in the early 70s -- and it was granted, and the clown who got it made a pile of money from it. However, software is a weird area in which to seek a profit from such a patent, because to enforce a judgment against a developer, the patent holder would have to compel him to reveal his source code -- and that takes a lot more than an unsupported claim of patent infringement.

                              But on the larger topic, the requirements for a patent grant are less stringent than you might think. Some years ago, a friend tried to patent the flight of stairs. He missed, but not by much!

                                      But an expired patent is certain proof of prior art.

                                        IBM was using linked lists in OS/360 in the late 1960s, and possibly in other operating systems before that. I would bet that they had already patented it, or thought it was too obvious to patent, or they just didn't do software patents then.
