Appeal 2007-1978
Application 10/185,702
invention unpatentable under 35 U.S.C. § 103(a)? Particularly, do these
combined disclosures render the claimed invention unpatentable given that
they teach storing transmitted messages in a queue?
FINDINGS OF FACT
The following findings of fact are supported by a preponderance of
the evidence.
The Invention
1. Appellants invented a method and system for transmitting data
in a switched network between a client and a server using an Ethernet
protocol4 in lieu of TCP/IP to route the data. (Title, abstract.)
2. Upon receiving a client’s request5 to read or access data in a
designated storage device, the server reads and accesses the data through one
read request when the requested data is stored in contiguous sectors of the
storage device.6 (Specification 15.)
4 The protocol is based on fixed-size linear arrays of sectors. All protocol
parameters are in terms of sectors. Request and Response payload data are
clustered in blocks of contiguous sectors of 512 bytes. (Specification 12.)
5 Length field 616 is used to indicate the length of the request or response in
sectors and sector identifier field 618 identifies the first sector.
(Specification 14.)
6 The response maintains the values in the request and fills in the device size
in sectors per request in the length field 616 and the initial request window
size in the flow control field 614. (Id.)
