Access, Fixed and Optical Networks Technology Cluster Overview:
- Includes 517 total patent families, with 942 total assets (including 332 active issued US patents, 238 active foreign counterparts (JP, KR, AU, TW, GB, FR, SE, IN, DE, EP, CN, CA, IT))
- Earliest filing: 1998-01-12
- Average lifespan: 6.0 years
- Covers optical networks and transport, SONET/SDH (transfer over optical fiber), passive optical networks (PONs), and microwave transmission
- Also addresses home and access networks, including modems, terminals, PBX, and POTS transmissions
The Access, Fixed and Optical Networks Technology cluster includes 942 patents with claims covering areas including virtual reality, data processing, resolving issues between dissimilar databases, video coding, display techniques, and addressing broad areas of telecommunications systems and wireless networks. This cluster includes assets with a lifespan to 2035.
One measure of cluster quality is the number of forward citations to the assets offered. The following chart illustrates the number of forward citations for this portfolio, and include lines representing citations in the USPTO by others and in litigation by others. The averages for litigation and USPTO citation are shown by lines sloping slightly upward from the lower left corner, and for the time period after 10 years from publication, the number of forward citations increases dramatically. Again,
this serves to confirm the value of the patents in this cluster.
The following charts illustrate relative quality score, claim quality score, lifespan, and classification breakdown of this cluster. Of note is the relative number of “very good” assets based on overall quality score, a measure of claim word length, forward citations, lifespan and relative class valuation. As may be seen from the following representations, a high number of assets with “Excellent” or “Very Good” claim quality scores are offered in this cluster.
