For selling patents, try to create a family of commercially useful patents that are hard to design around and legally strong. Know your market!
Although patents are best used to help inventors and startups attract funding and protect their products from copycats, sometimes the barriers to commercialization are just too high. Thus occasionally, alternative patent monetization approaches, such as sales, licensing, or litigation; may be a potential alternative. Here I discuss selling patents in a non-litigation context. Licensing and litigation will be discussed in later articles.
Your patents need to have good commercial potential, or else the game stops right here. The considerations include potential market size, market share, and value added by the patents. The patents have to be “strong” (e.g. not easily invalidated on the basis of prior art, and not have a lot of loopholes).
To understand selling patents, consider the subject from the standpoint of a potential corporate purchaser. With the exception of “blocking patents” (which are relatively rare), for any given single patent, the corporate technologists will usually say “no problem, we can design around it”, and the corporate legal counsel will usually say, “no problem, we will come up with non-infringement/invalidity arguments”. Given this “no problem” input, if there is only one patent, the corporate decision maker will often decide to “risk it”, and if so, there will be no sale.
By contrast, when the corporate purchaser considers multiple patents, the assurances of the technologists and legal counsel decrease. Technologist assurances that “we can design around it” become more guarded. Legal counsel, realizing that it may have to challenge multiple patents, will add up the potential costs and risks of multiple potential court cases, and also be less reassuring. This is why, even for the strongest patents, most patent sales take place in the context of a family of related patents.
Patent valuation, and comparables: Although you may be tempted to put your pinky in your mouth and say “one hundred billion dollars”, market realities should be considered. Just as there are real estate “comps” (average selling prices of houses in a neighborhood) and real estate valuation schemes, so there are “patent comps” and various techniques to measure patent valuation. Corporate purchasers have to justify their expenses to their upper management or their board of directors. This justification becomes harder as the patent price moves outside of typical comps and valuation schemes. So it is important to be aware of these comps and valuation schemes, and set your expectations and negotiating strategies accordingly.
Selling methods: There are various methods of selling patents, including direct corporate deals (the traditional method), online auction sales, sales using brokers, and sales to NPE (non-practicing entities – formerly big, lately less active). As in any financial transaction, it is helpful to try to position yourself to negotiate from a position of strength (e.g. have financial means to walk away from bad deals) and to approach the transaction in an informed manner.
