Washington, D.C. NFL Team Loses Race to the Trademark Office: Does it Matter?
IPWatchDog
In surveys throughout the Washington, D.C. metro area, three possible replacement names have emerged as favorites among the fans: Warriors, Red Wolves, and Redtails. Armed with the knowledge of the name change and the relative popularity of the possible replacement names, two enterprising individuals have applied to obtain a federal trademark registration for the marks WARRIORS, WASHINGTON RED WOLVES, and WASHINGTON REDTAILS, respectively. Neither applicant appears to be connected to the owners of the Washington D.C. professional football team.

The relative stability of trpzip1 and its mutants determined by computation and experiment
RSC Advances
Six mutants of the tryptophan zipper peptide trpzip1 have been computationally and experimentally characterized. We determine the varying roles in secondary structure stability of specific residues through a mutation assay. Four of the mutations directly effect the Trp–Trp interactions and two of the mutations target the salt bridge between Glu5 and Lys8. CD spectra and thermal unfolding are used to determine the secondary structure and stability of the mutants compared to the wildtype peptide. Adaptive steered molecular dynamics has been used to obtain the energetics of the unfolding pathways of the mutations. The hydrogen bonding patterns and side-chain interactions over the course of unfolding have also been calculated and compared to wildtype trpzip1. The key finding from this work is the importance of a stabilizing non-native salt bridge pair present in the K8L mutation.

Case Law as a Guide to Trademark Ownership, Licensing and Enforcement
World Trademark Review
Under common law, ownership is conferred through first use of a trademark– including use by a licensee. Recent case law can help to determine which party has the right to enforce the licensed mark where an infringement suit arises.

Mutational Analysis of Neuropeptide Y Reveals Unusual Thermal Stability Linked to Higher-Order Self-Association
ACS Omega
Neuropeptide Y (NPY) is a 36-residue peptide, abundant in the central and peripheral nervous system. The peptide interacts with membrane-bound receptors to control processes such as food intake, vasoconstriction, and memory retention. The N-terminal polyproline sequence of NPY folds back onto a C-terminal α-helix to form a hairpin structure. The hairpin undergoes transient unfolding to allow the monomer to interact with its target membranes and receptors and to form reversible dimers in solution. Using computational, functional, and biophysical approaches, we characterized the role of two conserved tyrosines (Y20 and Y27) located within the hydrophobic core of the hairpin fold. Successive mutation of the tyrosines to more hydrophobic phenylalanines increased the thermal stability of NPY and reduced functional activity, consistent with computational studies predicting a more stable hairpin structure. However, mutant stability was high relative to wild-type: melting temperatures increased by approximately 20 °C for the single mutants (Y20F and Y27F) and by 30 °C for the double mutant (Y20F + Y27F). These findings suggested that the mutations were not just simply enhancing hairpin structure stability, but might also be driving self-association to dimer. Using analytical ultracentrifugation, we determined that the mutations indeed increased self-association, but shifted the equilibrium toward hexamer-like species. Notably, these latter species were not unique to the NPY mutants, but were found to preexist at low levels in the wild-type population. Collectively, the findings indicate that NPY self-association is more complex than previously recognized and that the ensemble of NPY quaternary states is tunable by modulating hairpin hydrophobicity.

Prior Art Takes New Shapes: Relying on Non-traditional Prior Art to Invalidate a Patent
Pharmaceutical Patent Analyst
When we teach kids today about Internet privacy, one of the things that is emphasized is that once something has been posted on the Internet, that posting seemingly takes on a life of its own, with an eternal existence, even if the original poster deletes the posting. Unfortunately, companies have not learned this lesson and temporal items, such as press releases and Internet publications, can come back to haunt a patent owner in the form of invalidating prior art for a post-grant review. The following paragraphs consider ‘non-traditional’ prior art, for example, press releases, Internet publications, drug labels among others, and examine considerations in determining whether such non-traditional prior art can be used as a basis for invalidating a patent.

Pulse Electronics, Inc., 579 U.S. _____; No. 14-1513, the Supreme Court turned back the clock on increased damages under 35 U.S.C. § 284, ruling that the test adopted in In re Seagate Technology, L.L.C., 497 F. 3d 1360 (Fed. Cir. 2007) “unduly confines the ability of the district courts to exercise the discretion conferred to them.”
