I'm looking for economic terminology which must exist, although I don't know what it is. (I want to look up articles on a particular situation involving two real-world companies.)

Here is the situation: Company A is developing a diagnostic test which will warn of a particular type of deadly antibiotic resistance. Company B is a pharmaceutical company developing a drug to treat that kind of resistance.

Is there an economic terms that describe concepts relevant to this situation? The important features are that

1. Product B will never be bought without product A.
2. Customers will only buy A with the intention of possibly buying B.
3. Product B will certainly sell at a very high price if product A works perfectly, because A will identify those patients for which B is life-saving. A deserves some of this return, but the many customers buying A each will have only a low-probability of being one of the few to benefit.

Similarly, one could imagine a related case that there are exactly two bicycle wheel manufacturers, and by law A can only sell front wheels and B can only sell back wheels. There will be some sort of odd price hostility between A and B, because the two products are each useless without the other. The natural thing to happen is for A and B to merge, although wrangling about the terms of a merger may make this impossible.

In my real-world case the cognizant shareholders of A should oppose any buyout by B at anywhere near current market prices, because A's technology will extend to many many other applications.

Here is the situation: Company A is developing a diagnostic test which will warn of a particular type of deadly antibiotic resistance. Company B is a pharmaceutical company developing a drug to treat that kind of resistance. Company A needs to raise money, and company B is a large pharma with a market cap 1000 times as large as A.

Is there an economic term that describes this situation? The important concept is that when both products come to market, a customer will not know he need's B's product without access to A's diagnostic. Since A & B will be in direct price competition, it is highly likely that B will buyout A at some point.

This is a real-world example, and I'm trying to find the terms used to describe it.

It is to the advantage of the cognizant shareholders of A not to accept any sort of buyout. (Their technology will be useful in many other ways, yet the market is not giving proper value to the long-term applications.) It could be the case that A will have a similar situation with companies C, D, ect... one day.

To make matters more interesting, the existence of A's diagnostic will make B able to charge a premium price for their antibiotic. In particular, the diagnostic will warn the patient that he'll likely die without B's drug, upon which he'll be happily willing to pay whatever B asks.
