What is a java expert witness?

Java expert witness candidates typically have years of experience in computer science, software engineering, and/or computer engineering. The chosen expert could be a member of a technical industry organization such as The Software & Information Industry Association (SIIA), The Software Alliance, or the IEEE.

What types of cases require a java expert witness?

Often, Java matters requiring expert witness services involve intellectual property, such as patent infringement litigation, copyright infringement, or trade secret misappropriation. A software forensic expert has experience reverse engineering software code to determine if there is evidence to reveal intellectual property infringement or theft.

This expert has over 30 years of experience in computer technology and actively codes in C++, C, C++ CLR, Java, JNI, and C#, with extensive experience in database technologies.

  This expert applies these skills to compare sets of source code and identify circumstances where code may have been copied or where an application may violate a copyright or patent. This expert uses a manual comparison process that reviews each line of code and the architecture rather than relying on software tools. The process produces detailed reports for use in later litigation stages.

  This expert has copyright experience in matters in the United States and Canada, including the use of abstraction, filtration, and comparison to evaluate applications and processes. This expert has applied standards such as Substantial Similarity, look-and-feel protection, and the virtually identical standard to compare applications and processes.

  This expert has created detailed process flows, used screen captures, and compared system outputs to identify areas of commonality or demonstrate a lack of overlap.

This expert has also supported summary judgment work in software-related disputes.

  This expert has analyzed the use of open source code and its impact when used in developing an application. Open source code is often used to reduce development time or to include functionality outside a developer's existing skill set.

  This expert has considered legal implications associated with open source code, including the Digital Millennium Copyright Act and legal treatises addressing computer technology. This work has involved examining different license types, including GNU/GPL, Apache, and Android licenses.

  This expert has addressed the complexity of open source licensing, including how poor licensing choices or badly constructed licenses can create negative consequences for creators and users. Users of open source code need to examine the legal ramifications of such code to avoid negative impacts. This expert has opined that open source code can have both advantages and disadvantages and that users must understand the potential consequences of using it.

  This expert has evaluated alleged theft of intellectual property by examining systems for similarities in architecture, code, form flow, and function. This expert has considered opportunity, motive, deposition testimony, relevant skill sets, and whether a person accused of theft had the ability to take or copy code, documents, sales plans, or other material.

  This expert has examined security protocols of material owners to analyze whether alleged theft could have occurred and how it could have been done. This expert has collected this information and provided analysis in reports.

  This expert has supported software copyright matters involving web applications used for processing health insurance claims. The work included auditing applications, reviewing source code, interviewing technical personnel, studying allegedly infringing applications, and analyzing software copyright principles, including scenes a faire, abstraction, filtration, comparison, the virtually identical standard, and the substantially similar standard.

  This expert has analyzed business models, transaction flows, external data, data types, and process interactions to define the form, flow, and function of software applications and associated business processes. This expert has documented user interfaces, data fields, technology components, data items, data processing methods, and database structures, and has prepared detailed comparison reports addressing alleged copyright violations.

  This expert has also supported defense work in software copyright matters involving ATM, POS, check-image, and transaction-processing software. This work required knowledge of Java, Apache Camel, WebSphere, message queues, TCP/IP communications, remote-site connections, and Microsoft SQL Server.

  This expert has reviewed deposition testimony to validate or contradict technical claims, examined messaging formats used by financial transaction systems, analyzed data transfers using knowledge of TCP/IP, and evaluated interactions among card-processing entities to understand data-transmission protocols and message-format standards.

  This expert has provided knowledge of Check 21, the rule allowing images of checks to be treated as legally equivalent to paper checks, in connection with software capability analysis. This expert has performed line-by-line comparisons of software to source code alleged to have been copied and has analyzed copyright issues using public-domain and originality principles, U.S. Copyright Office materials, and form, flow, and function analysis.

  This expert has supported intellectual property theft matters involving software for large-scale prescription processing. This work included reviewing deposition testimony, evaluating skill sets, reviewing project plans, interviewing personnel, and applying experience in source-code security to assess whether theft allegations were technically supported.
