It could be (and I don't have authority to sign or to deny) that the figure of 1:10 000, be due to an accumulation of causes, for example:
* A company, he/she can understand that it patents something, knowing that it won't suppose him any economic benefit (direct), but it avoids this way that another company uses its system - method - invention; therefore the benefit is strategic, and not as a result of licensing the use of its patent.
* Other companies, they can simply want to patent their ideas that take applying during years, to avoid that other companies patent them, and then to seek to limit them the use, entering this way in litigations (it is another reason of strategies). It may to see it often , inventions that I call "fool", since that its patent, doesn't have utility some, its utility can be assumed exclusively strategic: to look at the quantity of office things that they maintain a patent (often as pat. pending) and that they are based on a design or structural physical model). Other times what is sought to avoid is the excessive resemblance in the products that other marks want to take advantage, to attract the client, for confusion or physical resemblance defining a wide margin of possibilities with the help of patenting models that look like each other enough to their original.
* there are certainly always completely useless inventions, for example a box that has the mold to house the different types of coins, so that once full the hole of each group of currencies, contain a concrete quantity of money. It is clear that an invention of this type, is feasible of being invented by anyone, and therefore to design a model different to the one proposed by other patents. Since the object of the invention is obvious (in this case), the only thing that will be been able to patent, is the product with what is manufactured, or the adopted physical form (that is the base I suppose with these devices they are patented), this way this types of inventions, I believe that they will never give benefits.
Maybe be mistaken in my positions, but the figure 1 among 10 000 I find high, if correct if it is used in figured sense wanting to indicate with it that should take care the invention, so that it is useful to their inventor (I suppose that this it is the idea that is in the mind of Mr. Auslander when he mentions this circumstance).
