received URL in the searched data structure, the received URL is processed
(Specification 2).
Humes discloses a system and method for filtering objectionable
subject matter from World Wide Web pages received by a computer system
connected to the Internet. A requested URL of a web page is compared to
an “allow list” or a “deny list” of URLs of web pages to, respectively, permit
or forbid access to the requested web page (col. 3, ll. 9-21).
Meyerzon discloses a Web “crawler” which establishes a searchable
index of documents by creating a history table, in a store which supports a
folder hierarchy, the table having a list of URLs found for each document
and folder found in the crawl. (Abs. ll. 1-14). A hash value (col. 4. ll. 59-
62) along with the contents of the document and time stamp information is
also stored in the index. When a new document is received, the history table
is searched to determine if the hyperlink URLs in the document are listed
within the history table and, if not, the URLs are added to the list in the
history table (col. 9, ll. 45-56).
PRINCIPLES OF LAW
1. ANTICIPATION
It is axiomatic that anticipation of a claim under § 102 can be found if
the prior art reference discloses every element of the claim. See In re King,
801 F.2d 1324, 1326, 231 USPQ 136, 138 (Fed. Cir. 1986) and Lindemann
Maschinenfabrik GMBH v. American Hoist & Derrick Co., 730 F.2d 1452,
1458, 221 USPQ 481, 485 (Fed. Cir. 1984).
In rejecting claims under 35 U.S.C. § 102, a single prior art reference
that discloses, either expressly or inherently, each limitation of a claim
invalidates that claim by anticipation. Perricone v. Medicis Pharmaceutical
