Supreme Court Hears Oral Arguments in TC Heartland v. Kraft Foods

On Monday March 27, the Supreme Court heard oral arguments in the case of TC Heartland v. Kraft Foods, a case that has potentially vast implications on patent venue, a fundamental issue in the area of patent litigation. Currently, patentees can bring suit in any district court, even if they do not have a business presence in that district. Whether this practice should continue or be overturned is the crux of the issue heard at the Supreme Court.

Enhanced Oil Recovery Patents – 2016 (Part 1) Microbial/Enzyme Enhanced Oil Recovery

This is an article in a series reviewing 2016 patents focused on Enhanced Oil Recovery (EOR). In particular, this article relates to the technology area of Microbial Enhanced Oil Recovery (MEOR), which concerns the use of microbes to extract oil from oil-containing formations, and Enzyme Enhanced Oil Recovery (EEOR) which similarly concerns the use of enzymes.

Dilworth IP Sponsors 4th Annual Yale Graduate Biomedical Career Fair

Dilworth IP is proud to sponsor the 4th Annual Yale Graduate Biomedical Career Fair, which will be held on Tuesday, March 28th at Yale University’s Harkness Hall in New Haven, CT. The event, which is hosted by the Yale Biomedical Careers Committee (BCC), offers Yale biomedical graduate and postdoctoral students an opportunity to explore a variety of potential career opportunities, hear from Yale alumni who have successfully transferred the studies into non-academic careers and network with business professionals.

U.S. Ranked #1 on Chamber of Commerce 2017 IP Index

Last month, The United States Chamber of Commerce (USCC) released the 5th Edition of the International IP Index, entitled “The Roots of Innovation”. The Index, which posts on the USCC’s Global Intellectual Property Center (GIPC) website, was established to highlight the importance of intellectual property (IP) in catalyzing economic growth and development, as well as to cultivate healthy competition between nations. In the current Edition, David Hirschmann, President and CEO of the USCC GIPC, likens IP to a tree. “Just as a tree cannot grow without roots, innovation cannot thrive without intellectual property.” At the most basic level, IP leads to job creation (statistics can be found here on the GIPC website). On a larger scale, IP promotes cross talk and collaboration between multidisciplinary fields, such as medicine, science, and finance.

Thinking About a Career as a Patent Attorney? Michael Dilworth’s Interview Offers Some Insights

Michael Dilworth, Founder and Managing Partner of Dilworth IP, was recently interviewed by Tianyi Yua at the Career Network for Student Scientists and Postdocs at Yale (CNSPY) about what one might expect in a career as a patent attorney. The CNSPY was established in 2011 as a platform for Yale graduate and post doctoral students to explore career options and build a professional network. In the interview Mike discusses the skills required to work in the field of intellectual property, explains his own career path, and outlines a typical day at work for a patent attorney.

The IP Manager’s Playbook: Leveraging the Tools of the USPTO, Part I – Awaiting the Return of P3

In July, 2016 the Patent Office initiated the Post-Prosecution Pilot program (P3), designed to reduce the use of RCE’s and the pendency of applications, as well as to improve the collaboration between applicants and Examiners. The program ended this past January, when the six-month time frame for the test program was reached. While the program’s results are currently being reviewed by the Patent Office, in view of its popularity, there’s a good chance that the P3 program will be reconstituted in one form or another. It’s worth taking another look to review what the program was all about.

The FDA Releases Guidance on Interchangeability

In January, the United States Food and Drug Administration (FDA) released a draft guidance entitled, “Considerations in Demonstrating Interchangeability” aimed at helping to implement the Biologics Price Competition and Innovation Act of 2009 (BPCIA). This guidance serves to directly address the issue of demonstrating interchangeability of biological products and the standards required to do so. Interestingly, no product has yet been shown to be interchangeable, including the four biosimiliars that have already been approved by the FDA.

Nanomedicine: A Vast Horizon on a Molecular Landscape – Part VIII, Magnetic Nanoparticles theranostics

Magnetic nanoparticles, also known as superparamagnetic nanoparticles are small inorganic crystals about 5-20 nm in diameter. Two main classes of MNPs currently used for clinical imaging are ferromagnetic iron oxide nanoparticles and ultrasmall superparameganetic iron oxide nanoparticles (USPION). MNPs are usually multilayer materials, which give them their various properties and functionalities for diagnosis and disease treatment. The structure of iron oxide nanoparticles has three main components: an iron oxide core as a Magnetic Resonance Imaging (MRI) contrast agent, a biocompatible coating outside the core, and an outer therapeutic coating with specific ligands for biomarker targeting. See (US 8,945,628 by Dr. Ralph Weissleder at Massachusetts General Hospital and US 7,462,446 by Dr. Miqin Zhang at the University of Washington). This unique structure enables MNP accumulation in the sites of interest via biomarker targeting. It further allows the diagnosis of diseases, the evaluation of treatment efficacy, and the localized delivery of drugs and disease therapies. The integration of both diagnostic and therapeutic modalities into one single agent is called a theranostic agent. We will discuss the diagnostic and therapeutic properties of MNPs in cancer.

Dr. Jing Zhou of Dilworth IP is Promoted to Patent Agent

Dilworth IP’s Dr. Jing Zhou has been approved to practice before the United States Patent & Trademark Office, and is now a registered Patent Agent. Dr. Zhou has earned her doctorate from the University of California, Berkeley in Mechanical Engineering with a focus on biomaterials. She later pursued postdoctoral research at the National Institute of Standards and Technology (NIST) in a variety of areas including biomaterials, nanocomposites, energy storage devices and live cell-nanomaterial interface. She has held a position as Associate Research Scientist/Lecturer at the Yale School of Medicine, and currently also serves as Review Editor for Frontiers in Bioengineering and Biotechnology. “Jing has been a great addition to the firm with an incredible knowledge in several advanced technologies, and a dedicated work ethic,” commented Dilworth IP Founder, Michael Dilworth, “with her recent certification as a patent agent, I look forward to seeing her role here grow.”
