"over 20k people (total company approx. 110k) the sales department being the biggest department in the company, research has 14k people for example. Based on your comment, what you know about business model analysis we can written on the back of a postage stamp.. however to give credit where it's due, based on your profile picture you'd possibly be more knowledge in steroid abuse."''

Have no idea if those figures are accurate or not, but there is one thing I am sure of, which is this:
"In our empirical analysis of the financial accounts of 27 of the largest global pharmaceutical corporations for the years 2000–2018, we find evidence of a shift in Big Pharma’s business model from one focused on productive capacity (reflected by fixed capital and R&D) to one focused on intangible assets (reflected by patents, brands and goodwill). The modus operandi of Big Pharma is one that increasingly resembles that of a private equity fund that generates returns for shareholders that are supported by monopolized knowledge through intellectual property rights, capitalized future earnings potential and rising debt burdens."

In short, Pfizer may be just monopolizing intellectual property rights by going into the market place where those rights are being traded, by either buying such rights or by absorbing the little companies holding them.

Have we ever been approached by somebody with a big cheque book?
