Frequently Asked Questions

A patent infringement claim chart is a visual representation of evidence showing how each claim limitation has been implemented by an infringing product or service. It is an essential artifact during any patent licensing or enforcement campaign, as it articulates the infringement theory in an easy to understand and difficult to refute format.

A typical patent infringement claim chart costs between USD 500-3000, depending upon number of claims, claim complexity and the technology. Depending on volume, we also price claim chart projects either on an hourly rate or on a fixed-price basis. Read more "When Claim Charts Do More Harm Than Good For Patent Litigation and Licensing"

A good patent infringement claim chart takes 5-8 hours. Copperpod IP prepares litigation ready claim charts to serve our clients at the speed of need. The chart provides detailed analyst comments explaining how the evidence shows that the charted product or service implements the claim limitation, and annotations highlighting the most important portions of the cited evidence.

Evidence for a claim chart can come from a variety of sources, such as product manuals, product videos, technical standards, network packet captures, product tear down and reverse engineering, product testing and demonstrations and even source code of the software running on the product.

Depending on the jurisdiction and particular case details, a single claim chart can cover multiple products, though these products would usually be substantially similar to each other. Read more about the target scouting process.

Yes, expired patents can be enforced. The condition is, if the infringement happened during the active period of the patent then you have the right to sue for damages accrued over that portion of the active period - provided also of course the damages have accrued within the time allowed by the statute of limitations.

Yes, wherever applicable, Copperpod's patent infringement claim charts include hard-to-find and harder-to-refute evidence. We use a variety of Reverse Engineering (RE) techniques such as SEM, TEM, EELS, EDX, and packet sniffing to furnish such evidence of use.

Yes, wherever applicable, Copperpod's patent infringement claim charts include source code review evidence. Copperpod's source code experts navigate through the source code using specialized tools and software and are well versed in all modern programming languages and platforms.

Yes, discontinued products can be charted for patent infringement. But due to the statute of limitations, you may not be able to recover damages beyond a certain time (often, 5-10 years) before the complaint for patent infringement is filed with the relevant court.

A prior art search (also called a patent search) reveals whether (or which portions of) an invention is truly novel and truly non-obvious, in light of all published literature (including patents, technical papers, products, manuals, even university theses).

A typical prior art search costs between USD 1000-3000, depending upon number of claims, claim complexity and the technology. Depending on volume, we also price prior art search projects either on an hourly rate or on a fixed-price basis.

A patent literature prior art search report typically takes 3-4 days. An exhaustive prior art search (including non-patent literature) report could take from 5-8 days. Copperpod IP prepares an invalidity search report which is keyword based, citation based and inventor based search report and it contains result feature matrix, claim by claim mapping, detailed analyst comments explaining how the prior art shows that the patented claims are invalid, and annotations highlighting the most important portions of the cited prior art.

Evidence for a prior art search can come from a variety of sources, such as : Patent databases (USPTO, EPO, CNIPA, JPO, IP Australia, IPOS, IPO, WIPO and nearly a 100 other jurisdictions) Non-Patent literature database (IEEE, ACM, ScienceDirect, SCOPUS, ITU-T, Google Scholar, Amazon, Google Books and many more) Product manuals, product videos Technical standards Product teardowns Source code of the software running on old products

Yes, our prior art search report covers NPL (Non-Patent Literature) database as well, such as IEEE, ACM, ScienceDirect, SCOPUS, ITU-T, Google Scholar, Google Books and Scribd, PubMed, IBM-TDM, GlobalSpec, COMPENDEX, SIAM Amazon, Infibeam, eBay Internet Archives Product manuals, product videos and demonstrations, Technical standards Product teardowns Source code of the software running on old products

Yes, our prior art search report provides analysis covering top anticipatory prior art as well as possible prior art combinations for showing how an invention may have been obvious in view of the various prior art combinations.
