Analyzing the merits of Internet and cloud computing software for patent validity and infringement often demands a sophisticated knowledge of the relationship between applications and their underlying communications service architecture.

Dr. Lavian’s academic and industry experience with the Internet and cloud computing—especially the OSI model as implemented through the TCP/IP stack—gives him a keen understanding of the logic behind business software as well as its component application, transport, network, data link, and physical layers. His expertise also extends to the hybrid architectures of legacy enterprise software systems.

Drawing on his experience designing and executing real-world network software, Dr. Lavian is conversant in:

  • Architecture: web and client-server, cloud and distributed computing, peer-to-peer networking, virtual private networks, tunneling, content networking, network security and mobile applications
  • Internet protocols: HTTP, e-mail, SMTP, POP, IMAP, FTP, Telnet, SSH, SNMP, DHCP, DNS, NNTP, POP, SIP, IPv4, IPv6, UDP, TCP and IPSec
  • Programming languages and Software: Java and C/C++ plus software APIs, streaming, network management and content networking

When litigation concerns Internet or cloud computing software or architecture patents, copyrights or trade secrets, as an expert witness Dr. Lavian stands ready to review, analyze and compare underlying source code. In serving plaintiffs and defendants alike, his previous contributions have numbered Inter Partes Review (IPR) reports before the Patent Trial and Appeal Board (PTAB), patent infringement expert reports, depositions, and testimonies before both judge and jury.

  • Mobile application using cloud service APIs, Amazon Web Services (AWS), Google Cloud Services (GCP), machine learning libraries, AI and Python that enables a smartphone to search phone trees like Google searches the Internet.
  • Data-Center Communications: network and server orchestration
  • DRAC: SOA-facilitated L1/L2/L3 network dynamic controller
  • Open platform: project for the US Air Force Research Laboratory (AFRL)
  • Network resource orchestration for Web services workflows
  • A proxy study between Web/grids services and network services
  • Streaming content replication: real-time Audio/Video media multicast at edge
  • Packet capturing and forwarding service on IP and Ethernet traffic
  • CO2: content-aware agile networking
  • Active networks: US DARPA-funded research program
  • ORE: programmable network service platform
  • JVM platform: Java on network devices
  • Web-based device management: network device management
  • Designed and developed network communications software products in C/C++ –
  • Invented and implemented a two-way paging product –
  • System and network communications in C/C++
  • Real-time software and algorithms in C/C++ and Pascal

It is challenging to understand the specifics of a full application stack from the business logic, through the application layer, the transport and network layers, the data links, and the physical layers. Dr. Lavian’s unique skills cover the full architecture spectrum from the enterprise application, through the cloud infrastructure to the nuances of communication protocols that connect them including the physical layer.

This breadth of technical experience allows Dr. Lavian to get involved as an Internet and Cloud expert witness in a software or architecture patent, copyright, or trade secret case, as well as review, analysis, and comparison of the underlying software source code.
