I'm a "micro entity" and I'm considering patenting my idea myself.

I know that the language of the patent application is very special, eg. no limiting language should be used.

In some patent applications I see some texts that aren't part of the invention's description, rather, they aim to make sure that none of the language or terms used can be considered as limiting.

My question is: can I simply copy such generic texts from another inventor's application, and use them in my application?


The foregoing is merely illustrative of the principles of this invention and various modifications can be made by those skilled in the art without departing from the scope and spirit of the invention.


It will be apparent to those of ordinary skill in the art that methods involved in the present invention may be embodied in a computer program product that includes a computer usable and/or readable medium. For example, such a computer usable medium may consist of a read only memory device, such as a CD ROM disk or conventional ROM devices, or a random access memory, such as a hard drive device or a computer diskette, or flash memory device having a computer readable program code stored thereon.


It is understood that the various features, elements, or processes of the foregoing figures and description are interchangeable or combinable to realize or practice the invention describe herein. Those skilled in the art will appreciate that the invention can be practiced by other than the described embodiments, which are presented for purposes of illustration rather than of limitation, and the invention is limited only by the claims which follow.

Yes - you can use the boilerplate paragraphs. They likely won't hurt you but are unlikely to help you much. If you get a judge who thinks you "only get what the inventor actually invented" it doesn't add anything specific to the disclosure to enlarge the scope of what the judge decides you "actually invented". If you get a judge who thinks you get what the claims say (the correct position in my opinion) you are home free even without the boilerplate, assuming everything else in your application is solid.

Better to add, after describing each element of the invention, something like: " . . . or it could be made of wood, or plaster of paris; it could be made in a unitary fashion or it could be made of constituent elements of varying compositions.. . . ". Your second example is along these lines.

Or add something like: "the handle and the base could be distinct elements or the base can have a shape allowing it to also be the handle." These variations take thought about what the core of your invention is and how it could be embodied other than how you are initially envisioning it.

You mention that the language of a patent application is very special. True, and the question you are now posing is the least of it. In some places you do need to be specific, in others you need to be general. I highly recommend studying David Patterson's book Patent it yourself. I also recommend after reading it to not then actually do that.

Writing a reasonable patent application is hard and the pitfalls are many even for someone who has studied patent law and procedures.

  • Thanks for this clear explanation. To achieve what is described as "hybrid claim" in patents.stackexchange.com/a/529/25445 is there the need for some boilerplate or it should in theory be fine without?

    The wording "circuit configured for" that Professor Crouch mentioned is still workable language in a claim. Note that since that post in 2012 various court decisions have made functional claiming more problematic. You might look at a post in his famous patent blog a few days ago patentlyo.com/patent/2021/02/…

First the usual caveat: I'm going to mention a few bits of law here that are almost certainly specific to the US. It almost certainly doesn't apply at all outside the US.

In my opinion, your first example is almost completely meaningless, at least as far as affecting what a court is likely to decide about your patent. It's simply stating what's essentially a fact of patent law, already well known to any judge who's at all competent.

Giving more specific alternatives in the specification, such as in your second example, can have considerably more effect. This is especially true if your claim is written as a means + function limitation (wording like "means for X"). The supreme court has ruled that such a limitation is so general that it cannot/should not be taken literally as covering any possible means for carrying out the specified X. Rather, it is to be treated as a reference to the specification, and those means cited in the specification for doing X.

As such, if you have a claim limitation like "means for storing data", and the only storage listed in your specification is a hard disk drive, then the proper reading of the claim is that "means for storing data" that should be treated as literally meaning "a hard disk drive." On the other hand, if your specification lists alternatives such as "hard disk, ROM, Flash, or CD-ROM", then the literal meaning of "means for storing data" would be "hard disk, ROM, Flash, or CD-ROM", within the scope of that patent.

By contrast, an apparatus claim that included (for example) "a data storage device" as a limitation should not be limited in the same way. In such a case, it would (probably1) be proper to construe any of the above storage devices as falling within the literal meaning of "a storage device", even if the only storage device cited in the specification was a hard disk.

That said, I should add that the patent specification is also properly treated as a source of definitions of terms used in the claims, if the meaning of those terms is not clear from the claims themselves. As such, if a claim uses a term that would not have been known to a person of ordinary skill in the art at the time of the invention, then it's perfectly correct to look to the specification to see if the specification defines that term -- and if so, the definition within the specification should prevail over definitions from external sources.

I should probably also add that it's not always obvious whether a limitation is really a means+function limitation or not. For example, a few years ago there was a case where a claim used the phrase (going from memory here) "perforating means". Based on the subject matter, it was pretty clear that this really referred to something like "perforations", not something like "a machine for producing perforations." In any case, the patent specification cited not only perforations, but a number of other methods of weakening material along a line to provide a place that was easy to tear. The case went (at least) as far as the Court of Appeals for the Federal Circuit, with the only real disagreement being over whether "perforating means" qualified as a means+function limitation or not. Even within the CAFC, the decision on that wasn't unanimous. They decided it was a means+function limitation, but Judge Rader wrote a dissenting opinion.

1. "probably" hinting at the possibility that it depends on the subject area of the patent. For example, if the patent were about individual cells in a DRAM chip, "data storage device" might mean something like "a capacitor".
