I have significant experience in the area of US patents – I have written many patents, developed claim charts and helped in litigation for many years as Patents  Subject Matter Expert (SME). I have also developed proprietary software for large patent portfolio analysis.

I am also consultant on Patent Portfolio Analysis and Valuations.

A patent is an intangible asset. It reflects a holder’s right to profit from an invention. Owning the rights in a patent, however, does not equal actual cash flow unless you take additional steps to monetize those rights. Monetizing changes your intangible asset — the patent — into a stream of revenue. Patent monetization has become increasingly important as companies realize that a properly managed patent portfolio in this technological and Internet-driven age can sometimes generate more income than ordinary operations.

Claim Charts or Evidence of Use (EoU) Development

I have developed or evaluated over  500+ claim charts on different  products (SIP, VoIP, Web Application, Streaming, Security, Micro-Controller, USB, Flash Drive, IOT technologies).

        Evaluated large portfolios of thousands of patents for useful patents and for their infringement or market potential.

Patent Infringement Litigation Support and Expert Witness

I have provided litigation support and expert witness in the patent dispute involving industry leader like Apple, Motorola etc..

Selected Patents Filed and Granted

  • UPnP mobility extension using session initiation protocol

Patent date Issued Apr 7, 2005 Patent issuer and number us 20060245403

Patent description A mobility architecture is provided for use in a home network environment. The architecture includes: a mobile network device configured to remotely register with the home network upon attaching to a different network environment; a mobility support server operable to establish an address link between the mobile device and other network devices associated with the home network upon receipt of a remote registration request from the mobile network device; and a SIP server which cooperatively operates with the mobility support server to forward messages between the mobile device and the other network devices using a Session Initiation Protocol (SIP).

  • Patent title: Method of multicast file distribution and synchronization

Patent date Issued Jul 1, 2001 Patent issuer and number us 6,269,080

Patent description The present invention involves a method for multicast file distribution and synchronization in data networks. Specifically, the present invention includes a mechanism for efficient and reliable distribution of a data file from a single source to a large number of receivers using multicast distribution in wide area networks. The multicast file distribution is done by designating a receiver as an active receiver. The active receiver is selected using a novel token granting procedure. Once selected, the active receiver is responsible for generating retransmission requests as well as providing flow control feedback to the server during data transfer. All receivers on the network are offered a chance to become an active receiver in a controlled manner, and only one receiver can be an active receiver at any given time. This process continues until there are no receivers in the group with missing data segments. The second part of the protocol provides synchronization of the file version to ensure that all receivers have the last distributed version of the data file. In addition, the protocol allows newly joined receivers to request the file from the server. The protocol is suitable for applications where a server periodically distributes a new version of the data file to receivers in the network. In addition, the protocol can be deployed with or without the support of Internet Protocol (IP) multicast technology, and is not tied to any particular network topology or transmission medium.


  • Patent title: Cross layer optimization for improving tcp performance in lossy wireless environments

Patent date Filed Jun 28, 2007 Patent issuer and number us 20070147249

Patent description The present invention relates to improving TCP performance and, more particularly, to a method for reducing packet loss using cross layer information during data transfer.


  • Patent title: Light weight service discovery protocol

Patent date Filed Feb 26, 2006 Patent issuer and number us 2007/0195760

Patent description A service discovery protocol is provided for use in personal area networks and other ad-hoc networking environments. The service discovery protocol is specifically designed to take into account the dynamic network configurations, bandwidth constraints as well as other characteristics of these types of networks. One of the key differentiators of the service discovery protocol is that it relies on a dynamically selected service directory device to manage the amount of information being distributed in the network.


  • Patent title: Application session resumption in mobile environments

Patent date Filed 2006 Patent issuer and number us 20060291481

Patent description The present invention relates to seamless mobility support in data networks, and more particularly, to maintaining or continuing sessions for applications after connectivity disruptions or an application session is moved from one device to another device (e.g., from a cellular phone to a PDA).


  • Patent title: Policy-based device/service discovery and dissemination of device profiles in personal area networks

Patent date Filed Apr 25, 2005 Patent issuer and number eu 2006/0239190

Patent description A discovery framework model includes policy information in the device/service discovery protocols. Service discovery protocols are enhanced by embedding policy information in the over all discovery framework. A method of performing policy-controlled device/service discovery includes modeling a device/service discovery protocol with a state machine either at a gateway or at discovery agents. Policies are used to control and propagate device/service discovery information. These policies are sets of rules that define conditions and attributes under which a certain action is permitted or denied.
