According to the jury verdict, Google infringed two claims in the patent. The first claim describes an information storage and retrieval system comprising:

    a linked list to store and provide access to records stored in a memory of the system, at least some of the records automatically expiring
    a record search means utilizing a search key to access the linked list
    the record search means including a means for identifying and removing at least some of the expired ones of the records from the linked list when the linked list is accessed
    a means – utilizing the record search means – for accessing the linked list and, at the same time, removing at least some of the expired ones of the records in the linked list

The second claim also includes a "means for dynamically determining maximum number for the record search means to remove in the accessed linked list of records". The jury found that Google did not provide by a "preponderance of evidence" that these clams were invalid.


I'm neither a programmer nor a database person but doesn't this look a lot like fundamental database functions?  Is so then they are way too old to be under patent legitimately.
