Introduction

Understanding an inter partes review is essential for any professional in the patent field, from inventors to lawyers. This legal procedure allows a third party to challenge the validity of a previously granted patent, either because it was granted to the wrong person or because it is overly broad or vague. By presenting sound evidence to the Patent Trial and Appeal Board (PTAB), petitioners may be able to invalidate a patent, resulting in damages due for lost profits due to infringement.

It’s clear why this process is so important; if an overly broad or vague patent is allowed to stand, not only could innocent parties suffer infringement but confidence in the system would be damaged. To strengthen their case, petitioners can provide ‘prior art’ – any information that was publicly known before the filing of the patent. It’s critical that such evidence clearly demonstrates why the invention was not novel enough or inventive enough for its grant; this means careful preparation and presentation of material are essential if one wishes their rights as an inventor be fully protected.

The Genie AI team understands how challenging navigating this process can be – which is why we’ve developed open source legal templates specifically tailored for inter partes review proceedings. Using our datasets and community template library anyone can draft valid documents without requiring a lawyer’s expertise - no Genie AI account necessary! Our guide provides step-by-step guidance on how you can access our library today - so read on now!

Timeline for Completion of an Inter Partes Review

  • An Inter Partes Review typically takes 12 months to complete from the date the petition is filed
  • Once the petition is filed, the Patent Trial and Appeal Board (PTAB) has three months to decide if an IPR will be granted
  • If granted, the PTAB will issue a trial order with a schedule for exchanging initial disclosures and submitting motions
  • The initial disclosures should be exchanged within two months of the trial order
  • The parties must also submit their motions within the time period set by the PTAB
  • After the completion of the motion period, the PTAB will schedule a hearing
  • The hearing usually takes place within six months of the trial order
  • After the hearing, the PTAB will render a decision which is usually issued within three months

You will know when you can check this off your list and move on to the next step when you receive the PTAB’s decision on your Inter Partes Review.

Factors Considered in Making a Decision

  • The Patent Trial and Appeal Board (PTAB) will consider evidence from both sides regarding the patentability of the claims in question
  • The PTAB will look at the prior art and the arguments presented by each side
  • The PTAB will decide whether or not the patent claims are invalid based on the evidence presented and arguments made
  • The PTAB will also consider whether the claims are obvious or not in light of the prior art

You’ll know this step is complete when the PTAB has made its decision regarding the patentability of the claims in question.

FAQ:

Q: What are the key differences between an Inter Partes Review and a Patent Trial and Appeal Board review?

Asked by Ashley on the 11th of April, 2022.
A: An Inter Partes Review (IPR) is a process conducted by the Patent Trial and Appeal Board (PTAB) in which third parties can challenge the patentability of issued patents. The PTAB will determine whether or not the patent is valid in light of prior art that was not considered during initial examination. This is different from a Patent Trial and Appeal Board (PTAB) review, which is an appeal process for patents that have already been rejected by the USPTO. A PTAB review allows applicants to present new evidence or arguments to support their patent application, whereas an IPR does not.

Q: What are some of the advantages of opting for an Inter Partes Review?

Asked by William on the 28th of September, 2022.
A: An Inter Partes Review can be a cost-effective solution for challenging the validity of an issued patent. It is generally faster and cheaper than other avenues such as litigation in court, and can help reduce litigation costs if successful. It can also provide clarity on the validity of a patent before investing in expensive licensing or research and development costs associated with it. Additionally, due to its limited scope and expedited proceedings, an IPR may be more suited to complex patents than other legal methods.

Q: How does an Inter Partes Review compare to a Post-Grant Review?

Asked by Olivia on the 15th of February, 2022.
A: An Inter Partes Review (IPR) is essentially a re-examination of a patent’s validity based on prior art that was not considered during initial examination, whereas a Post-Grant Review (PGR) is an administrative process for challenging issued patents on any grounds, including prior art and anticipation. IPR proceedings are conducted before the PTAB, while PGR proceedings are conducted before the USPTO’s Board of Patent Appeals and Interferences (BPAI). Additionally, unlike IPRs, PGRs can be filed within nine months after patent grant and require payment of fees up front.

Q: What kind of evidence do I need to file an Inter Partes Review?

Asked by Emma on the 7th of March, 2022.
A: To file an IPR petition you will need evidence that demonstrates that one or more claims in an issued patent are unpatentable based on prior art that was not considered during initial examination. This evidence can take many forms including printed publications (such as books or journal articles), publicly available patents or patent applications, evidence from public use or sale, or any other material that could reasonably be considered by someone skilled in the relevant field as evidence of prior art.

Q: Are there any restrictions or limitations for filing an Inter Partes Review?

Asked by Michael on the 4th of May, 2022.
A: Yes - there are certain restrictions and limitations associated with filing an IPR petition. Firstly, you must file your petition within one year after being served with a complaint alleging infringement of the subject patent; secondly, you must demonstrate that you have standing to file an IPR; and thirdly, you must show that you are likely to prevail in your challenge to at least one claim in the subject patent. Additionally, there are restrictions around who can file an IPR based on USA jurisdiction - for example, only parties who have been sued for infringement can file for relief from infringement through IPR proceedings.

Q: Are there any differences between US and EU laws regarding Inter Partes Reviews?

Asked by Isabella on the 9th of June 2022.
A: Yes - there are significant differences between US and EU laws regarding IPRs. In Europe there is no equivalent process to US IPRs - instead companies will typically use other avenues such as litigation or invalidity proceedings to challenge patents they believe are invalid. The US also has more liberal rules around who can file IPRs - anyone who has been served with a complaint alleging infringement has standing to file an IPR petition in the US regardless of jurisdiction - whereas in Europe only parties directly affected by alleged infringement have standing to challenge patents through invalidity proceedings. Furthermore, while US IPRs are conducted before administrative tribunals such as the PTAB rather than courts, European invalidity proceedings are conducted before national courts in each Member State involved in the dispute.

Q: How much does it typically cost to file an Inter Partes Review?

Asked by Logan on the 1st of October 2022.
A: The cost of filing an IPR petition depends on how many claims you are challenging and how much evidence you need to submit in support of your challenge - typically between $15-$30k USD excluding attorney fees. There also may be additional costs associated with filing such as fees for filing documents electronically with eFiling services like EFS-Web or ESTTA/EDIS; fees for serving documents to all parties; fees for translating documents into foreign languages; attorney fees; expert witness fees; etc., so it’s important to factor these additional costs into your calculations when considering filing a petition.

Q: How long does it typically take for a decision to be made after filing an Inter Partes Review?

Asked by Avery on the 17th December 2022.
A: Generally speaking it takes around 18-24 months from filing your petition until you receive a final decision from PTAB following appeal (if necessary). However this timeline varies depending on factors such as how complex your case is; how many parties are involved; how much evidence needs to be considered; etc., so it’s important to factor these considerations into your timeline when planning for filing or responding to petitions filed against you. Additionally, if you find yourself in a situation where you need immediate relief from alleged infringement then it may be worth considering other legal options such as litigation which could provide quicker resolution than waiting for PTAB’s decision following appeal (if necessary).

Q: Are there any alternative solutions available if my petition is denied after filing an Inter Partes Review?

Asked by Mason on the 12th August 2022.
A: If your petition is denied then you may want to consider appealing PTAB’s decision before either Federal Circuit Court or Supreme Court depending on what stage your case has reached at time of denial - however this option should only be explored if there is sufficient grounds for appeal as it may incur additional costs which could potentially outweigh any benefits gained from successful appeal depending on individual circumstances so it’s important to weigh up pros and cons before making any decisions here. Alternatively you may wish to explore other legal avenues such as litigation which may provide quicker resolution than waiting for PTAB’s decision following appeal (if necessary).

Q: Does my country have any impact when filing an Inter Partes Review?

Asked by Joshua on the 23rd November 2022.
A: Yes - different countries have different rules and regulations around filing petitions for IPRs so it’s important to check local laws before proceeding with filing your petition especially if you plan to challenge patents issued outside USA jurisdiction e.g., if you plan to challenge European patents then you should check EU regulations around filing petitions for invalidity proceedings before proceeding with filing your petition etc., Additionally some countries may also have different timelines associated with filing/responding/appealing/etc., so it’s important to factor this into your timeline when planning for filing/responding/appealing/etc.,

Example dispute

Suing a Patent Holder for Infringement:

  • Plaintiff may raise a lawsuit citing a violation of the inter partes review process, claiming that the patent holder’s patent is invalid due to failing to comply with the process.
  • The plaintiff should provide evidence that the patent holder failed to comply with the inter partes review process. This could include submitting incorrect information, or failing to provide necessary evidence to make a case for their patent.
  • Depending on the strength of the evidence provided, the court may find that the patent is invalid due to the patent holder’s failure to comply with the inter partes review process.
  • If the court finds in favor of the plaintiff, the patent holder may be liable for damages caused by their infringement. The damages could include lost profits, legal costs, and any other costs incurred due to the patent holder’s infringement.
  • Settlement could be reached through a settlement agreement that could include payment of damages and/or the patent holder agreeing to withdraw the patent.
