Writing in Advanced Textiles Source, two patent attorneys share some basic advice on intellectual property rights. Mareesa Frederick and Mark Sweet of Finnegan LLP in Washington, D.C., note that a well-kept trade secret can offer far more protection than a patent:
"That protection, however, is not without risk as a savvy competitor could potentially reverse engineer and copy the trade secret. The scientist would then be left with no legal recourse. Whether or not to assume that risk depends on a number of factors: the ease of reverse engineering, the accessibility of the trade secret (is it part of the manufacturing process or apparent from the product itself), the likelihood of obtaining a patent, and the usefulness of the product after the patent has expired. The inquiry is highly fact-specific and one best addressed with an attorney."
U.S. patent 9181015 (applicant Raymond Booska, West Melbourne, Fla.):
"A liquid receptacle has an inner vessel for holding a liquid, an insulated outer shell spaced from the Miler vessel, and a chamber defined between the inner vessel and the outer shell. A phase change material is disposed in the chamber for absorbing thermal energy from the liquid and then releasing the thermal energy back to the liquid to maintain the temperature of the liquid. ...
"The present invention relates generally to liquid receptacles, containers, and accessories for such receptacles that rapidly cool a hot liquid to a warm range and then maintain the liquid in the warm range for an extended period."
Leo P. Kadanoff, a leading theoretical physicist best known for developing the concepts of "scale invariance" and "universality" as they apply to phase transitions, died Oct. 26 in Chicago. He was 78.Dr. Kadanoff, a professor at the University of Chicago from 1978 until his retirement in 2003, won the Buckley Prize of the American Physical Society in 1977, the Wolf Foundation Prize in 1980, the 1989 Boltzmann Medal of the International Union of Pure and Applied Physics, and the 1999 National Medal of Science.
Entropy Solutions, maker of PureTemp phase change material, won first place in two categories – blog and e-mail newsletter – in the 2015 Digital PR Awards.
Other finalists in the two categories included Coca-Cola, MasterCard, Polycom, Global Hotel Alliance and Adobe Systems.
The national competition, sponsored by PR News, recognizes the year's most outstanding digital communicators and campaigns. Winners were announced Monday at the annual Digital PR Awards luncheon at the Yale Club in New York City.
ArchiBlox, an Australian design-build firm that specializes in prefab buildings, has designed a sustainable house that can be assembled in just six hours.
"We call the house Carbon Positive, because we’re positively putting energy back into the grid," Bill McCorkell, owner and director of the Victoria-based company, said in an interview with The Fifth Estate. "This is due to the five solar panels mounted on the roof that produce electricity, and the fact that the house requires no mechanical cooling or heating.”
The 5-kilowatt-hour solar panels produce more than enough electricity to power the hot water system, LED lights and appliances. Excess electricity can be exported to the grid.
The home features double-glazed windows and slideable living walls and roof to reduce sun penetration as needed. Phase change material in the ceiling absorbs daytime heat and releases it when the temperature falls below 18° Celsius. The price for the one-bedroom, one-bathroom standard model: $286,000 AUD.
Italy's national soccer team will be sporting phase change material at the 2016 European Championships.
The team's new home jersey, which will make its debut Friday in a friendly against Belgium, features Puma's ACTV Thermo-R technology. Strategically placed tape infused with microencapsulated phase change material absorbs excess heat and releases it back to the body when needed. The tape is designed to provide a snug fit, "micro-massaging the skin in specific areas to provide a faster, more effective energy supply to the active muscles."

More than 430 of your peers have joined a new LinkedIn group devoted to the discussion of phase change material and thermal energy storage. The Phase Change Matters group is an interactive complement to the blog and newsletter of the same name.
You are invited to join the group and connect with PCM and TES experts from around the world. New members this week include Sajad Naghavi, Ph.D. candidate in energy engineering at the University of Malaya; Barry Kriha, marketing director at Plastilite Corp.; Marek Rebow, head of research of the College of Engineering & Built Environment at Dublin Institute of Technology; and Shamil Habib, CEO at FicusPax International.
Two Entropy Solutions advisors, Dr. Mohammed Farid of the University of Auckland and Lucas B. Hyman of Goss Engineering, are ready to answer your questions about phase change material and thermal energy storage. We'll select the best questions sent to email@example.com and post the answers here each Friday.
