There is no hotter technology than CRISPR-Cas9 gene editing tools. Perhaps it is not surprising then that there is a patent dispute over it, which falls into two camps: (1) Jennifer Doudna & Emmanuelle Charpentier, and (2) Feng Zhang. Who deserves the intellectual property for use of CRISPR-Cas9 in human cells? Take our poll.
The challenge to the WARF/Jamie Thomson patents/IP on human embryonic stem cells (hESC) is at an end. The US Supreme Court declined to hear the case. Earlier, the USPTO had turned down the challenge leading to a winding road in the courts. What do you all think of this stem cell IP challenge and the …

The still mysterious BioGatekeeper had challenged Yamanaka’s IPS cell patent claiming that it was obvious. The potential implications were huge given the commercial interest in translating IPS cell technology. For background see here, here, and here. There’s pretty much zero information on BioGatekeeper otherwise. Despite the potential seriousness of this patent challenge, just a few days …

Who is trying, via the name BioGatekeeper, Inc., to nullify Yamanaka’s patent on cellular reprogramming to produce induced pluripotent stem (iPS) cells? The readers of this blog never cease to amaze me. What an informed, energetic, bright group. Within just days they may have collectively shed some light on an intriguing mystery in the stem cell field surrounding the …

A new patent dispute has exploded in the stem cell field related to induced pluripotent stem (iPS) cells. What’s going on? In 2006, Shinya Yamanaka reported cellular reprogramming to create mouse induced pluripotent stem (iPS) cells in Cell and the next year multiple groups along with Yamanaka’s reported creating human iPS cells. It’s no exaggeration …

A new patent has been awarded to James Sherley for a very unusual method claimed for making induced pluripotent stem (iPS) cells. The patent, No. 8,759,098, claims that a single non-genetic chemical agent, xanthine, can by itself reprogram adult stem cells (ASC) into iPS cells (aka iPSCs; see image they released at left). Surprising patent, huh? Another …

People have been taking a long look over the last 24 hours or so at the STAP stem cell patent application filed by Charles Vacanti, his brother, Obokata, and others. Any reactions? I don’t know much about patents so I’d be curious of your impressions. New STAP paper troubles? I’m hearing through the stem grapevine …

If you’ve been paying attention to the stem cell world, you’ll remember Woo Suk Hwang, who nearly derailed the future of stem cell research by very publically proclaiming that he had made human embryonic stem cells by somatic cell nuclear transfer (SCNT). No, this has nothing to do with Shoukhrat Mitalipov’s report of successful generation …

A new article in the major Japanese newspaper, Asahi Shimbun, just came out suggest major intellectual property (IP) and patent issues related to stem cells including the new stress induced STAP stem cells. The piece is entitled provocatively enough “Global patent war looms with epoch-making discovery of STAP cells“. That’s strong language. The article begins …

Is Advanced Cell Technology (ACT) on the road to cure Multiple Sclerosis (MS) using stem cells and specifically MSCs? Some folks seem to think it’s quite possible, but I remain skeptical. Still there have been some interesting developments. ACT has a relatively new patent filing for a mesenchymal stromal cell (MSC) product that was just …
