SAMPLE CASE STUDIES

Datatek engineers have evaluated and examined products for patent licensing and litigation professionals in multiple technicaldisciplines.

Here are some examples of this work.

PC, PDA, AND HAND-HELD ACCESS DEVICES
Datatek engineers have been involved in acquisitions of numerous PC, PDA and Hand-held access devices from a variety of manufactures for analysis of a specific functionality of each device. Initially, an assessment of overall functionality and the human interface was performed on each device. Architectural reverse engineering of each product, ultimately expressed in block diagram format followed. Finally, specific functional blocks were evaluated where the construction of each block was examined in detail. Some cases involved physical reverse engineering and analysis of manufacturing methods or material aspects of the product. The results were presented as a formal report mapping the findings to the selected intellectual properties.

MP3 PLAYERS (MPEG AUDIO ENCODING/DECODING)
MP3 audio players were a subject of acquisition-and-analysis investigations. Each player’s encoding/decoding algorithms required reverse engineering to uncover potential patent infringement.

PATENT EVALUATION, INCLUDING APPLICATION TO PRODUCT USE
Datatek engineers are experienced reviewing and assessing patent portfolios and in searching patent and other intellectual property databases to obtain materials to be used for a specific product or product area.

COMPUTER GRAPHIC PROCESSORS
The operation and structure of a number of computer graphic processors were studied and evaluated. The information was expressed in a block diagram and mapped to selected intellectual properties.

DATA NETWORKING
Data networking equipment ranging from switches and routers to modems has been evaluated in the areas of, architecture, switching, queuing theory, cell transport, flow control, congestion, policing, quality of service, SNMP, and network management.

WIRELESS EQUIPMENT
Cellular telephones were another subject of acquisition-and-analysis investigation, including reverse engineering to identify and
analyze potential patent infringement.
