You are right, this is not referring to Spiber Inc. or anyone working there. This is referring to Japan’s National Institute of Agrobiological Sciences (NIAS). The researcher in the video, Yoshihiko Kuwana (not Kawata), refers to the silk that created the Vest and Scarf made from spider silk last year.
Looking at their PLOS ONE article, they used the piggyBac Transposon System similar to KBLB. I assume this is the international patent conflict that is hinted at in the KBLB filings. Looking at their numbers, they look only very slightly improved from the numbers in KBLB’s PNAS article, but since Kim stated that the MS numbers have been improved since then, I don’t think their properties are as good as the current strains of Monster Silk.
I do know that they are working with the Andhra Pradesh State Sericulture Research and Development Institute (APSSRDI) in India to help research and bring their silkworms to eventual commercialization as stated by TRUTH in his post #87225. I believe they still have some work to do and may need to eventually pay royalties to The University Of Notre Dame to ultimately commercialize, but I believe they are at least worth keeping an eye on.
