I will give you a good story about Roche and a company called IGEN. Roche used IGEN's technology in their diagnostic unit. It accounted for a billion in annual revenue for Roche. They clearly were under paying IGEN and eventually were infringing on the technology. It was tied up for years and finally went to court where IGEN won a $500 million settlement.
The judge came back and reduced the settlement to $50 million, but told Roche they had 10 days to cease and desist using IGEN's technology. The stock tanked into the the high $20's from $40, but a week later Roche had to buy out IGEN for $58 a share.
The amazing part was that IGEN only sold Roche that one unit and kept another unit. 2 years later Roche paid another $1 billion for the rest of IGEN's assets.
I only bring up this story because it shows how ruthless and unethical these Big Pharma's can be with a smaller company. They tied this up for years and some how IGEN was able to persevere. I'm in high tech and have watched MSFT team up with some small players with great technology with the promise of big $'s for the smaller company. Instead they ran the company out of business and picked up their technology for pennies on the $. Obviously, PPHM is in the ring battling it out and they might win, but they also are going to have a helluva fight slaying the beast. David vs Goliath and us shareholders are caught in the middle.
