Intellectual Property

Introduction

We strive to protect and maintain exclusivity for the proprietary technologies that we believe are important to our business, patients and shareholders. We are focused on pursuing and maintaining patent protection intended to cover core platform technologies incorporated into, or used to produce, our product candidates and commercial products. We will seek protection for our innovations in key global jurisdictions. We continue to focus our exclusivity strategies on all aspects of our assets, including our compositions of matter, methods of use for our approved products, and other inventions that are important to our business (e.g., the patient innovations described in our product labels/product inserts and our core manufacturing technologies).

Our intellectual property portfolio continues to grow and keep pace with the innovations arising from our discovery, development, and commercial efforts. We expect the total volume of patent positions under our management to increase with each year as our pipeline evolves. We currently oversee more than 500 pending applications and granted patents. More importantly, as we continue to innovate for patients, we will work to protect our patient innovations with new intellectual property filings to enable future reinvestment for patients.

In addition to patent protection, we rely on trademarks and trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection, including certain aspects of our llama immunization and antibody affinity maturation approaches.

Our commercial success depends in part upon our ability to obtain and maintain exclusivity, including regulatory exclusivities, patent, and other proprietary protection for commercially important technologies, inventions and know-how related to our business. We will defend and enforce our intellectual property rights, particularly our patent rights, and preserve the confidentiality of our trade secrets while operating without infringing valid and enforceable intellectual property rights of others. Specifically, we are materially dependent on regulatory, patent and other proprietary protection related to our core platform technologies, described in section “Platform Technologies”, and our product candidates, as described in section “Our Internal Programs” and section “Our Partnered Programs”.

The patent positions for biotechnology companies like us are generally uncertain and can involve complex legal, scientific and factual issues. In addition, the coverage claimed in a patent application can be significantly reduced before a patent is issued, and its scope can be reinterpreted and even challenged after issuance. As a result, we cannot guarantee that any of our platform technologies and product candidates will be protectable or remain protected by enforceable patents. We cannot predict whether the patent applications we are currently pursuing will issue as patents in any particular jurisdiction or whether the claims of any issued patents will provide sufficient proprietary protection from competitors. Any patents that we hold may be challenged, circumvented or invalidated by third parties.

The term of individual patents depends upon the legal term of the patents in the countries in which they are obtained. In most countries in which we file, the patent term is 20 years from the earliest date of filing a non-provisional patent application.

In the U.S., the term of a patent covering an FDA-approved drug may be eligible for a limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984 (Hatch-Waxman Act) as compensation for the loss of patent term during the FDA regulatory review process as described in section “Licensure and Regulation of Biologics in the U.S.”. Similar provisions are available in the EU and in certain other jurisdictions to extend the term of a patent that covers an approved drug. It is possible that issued U.S. patents covering each of our product candidates may be entitled to patent term extensions. If our product candidates receive FDA approval, we intend to apply for patent term extensions, if available, to extend the term of patents that cover the approved product candidates. We also intend to seek patent term extensions in any jurisdictions where they are available, however, there is no guarantee that the applicable authorities, including the FDA, will agree with our assessment of whether such extensions should be granted, and if granted, the length of such extensions.

Platform Technologies

With regard to our platform technologies, we own or have intellectual property rights directed to our SIMPLE ANTIBODY™ discovery platform, the ABDEG™ and NHANCE™ technologies.

With regard to our SIMPLE ANTIBODY™ discovery platform, we have a broad patent portfolio providing exclusivity on the SIMPLE ANTIBODY™ platform. We expect to enjoy exclusivity under this patent portfolio until between 2029 and 2033.

With regard to the ABDEG™ platform, we co-own the technology with UT Southwestern and enjoy certain exclusive license rights. We have a broad patent portfolio covering the composition of matter and uses of certain FcRn antagonists to achieve certain biological effects. The composition of matter and other relevant patents in the U.S. expire in 2036 whereas in many other countries the base expiry date is 2034.

With regard to the NHANCE™ platform, we exclusively licensed two U.S. patents from UT Southwestern with composition of matter claims directed to an IgG molecule comprising a variant human Fc domain, and method of use claims directed to a method of blocking FcRn function in a subject by providing to the subject such an IgG molecule. The U.S. patents are expected to expire earliest in 2027 to 2028. The patent family also includes a granted European patent.

Our Internal Programs

Efgartigimod

Efgartigimod incorporates the ABDEG™ platform technology. We anticipate several more patient innovations to evolve during development for which we will seek additional patent protection.

Our ARGX-109 Product Candidate

With regard to our wholly-owned ARGX-109 product candidate, we have one patent family with composition of matter claims directed to ARGX-109. The patent family has a basic expiry date in 2033. We anticipate several more patient innovations to evolve during development for which we will seek additional patent protection. Furthermore, ARGX-109 incorporates or employs the SIMPLE ANTIBODY™ platform technology and the NHANCE™ platform technology.

Empasiprubart Product Candidate

With regard to the empasiprubart product candidate, we own or have rights to multiple patent families (including one in-licensed patent family from Broteio) with several granted patents and pending patent applications in multiple jurisdictions in North America, South America, the EU and Asia, directed to composition of matter claims and method of treatment claims. The in-licensed patent family from Broteio has granted patents in several countries/regions and has a basic expiry date in 2034. Additional patent families have granted patents with basic expiry dates in 2039 and 2040. We anticipate several more patient innovations to evolve during development for which we will seek additional patent protection. empasiprubart product candidate incorporates or employs the NHANCE™ platform technology.

Our ARGX-119 Product Candidate

With regard to the ARGX-119 product candidate, we in-licensed patent families from/with NYU Langone Health, a U.S. medical center based in New York, and additional patent families from/with the LUMC, with a U.S. granted patent and several pending applications in multiple jurisdictions. We anticipate several more patient innovations to evolve during development for which we will seek additional patent protection.

Our ARGX-118 Product Candidate

With regard to the ARGX-118 product candidate, we co-own a patent portfolio with VIB, an inflammation research center in Ghent, Brussels, and Ghent University, with one U.S. granted patent and pending patent applications in multiple jurisdictions in North America, South America, the EU and Asia. The patent family has a basic expiry date in 2039.

Our Partnered Programs

Our Cusatuzumab (ARGX-110) Product Candidate

With regard to the cusatuzumab product candidate, we have a broad patent portfolio that include claims to the composition of matter, uses of the molecule, and other important inventions. The issued U.S. patents expire in 2032 and 2033, without taking a potential patent term extension into account. Cusatuzumab incorporates or employs the SIMPLE ANTIBODY™ and POTELLIGENT® platform technologies.

Our ARGX-115 (ABBV-151) Product Candidate

With regard to the ARGX-115 (ABBV-151) product candidate that we co-own with, and exclusively license from, the Ludwig Institute for Cancer Research and UCL, we have a patent portfolio that includes a U.S. patent with a basic expiry date in 2034, without taking a potential patent term extension into account. There is a second family with meaningful patent coverage to the composition of matter and epitope claims that are expected to expire in 2036 and 2038. Furthermore, ARGX-115 (ABBV-151) incorporates or employs the SIMPLE ANTIBODY™ platform technology.

Our ARGX-112 (LP-0145) Product Candidate

With regard to the ARGX-112 (LP-0145) product candidate, we have one patent family with composition of matter claims directed to an antibody that binds human IL-22R. The patent family has a basic expiry date in 2037. Furthermore, ARGX-112 (LP-0145) incorporates the SIMPLE ANTIBODY™ platform technology.

Trade Secret Protection

In addition to patent protection, we also rely on trade secret protection to ensure exclusivity for our proprietary information that is not amenable to, or that we do not consider appropriate for, patent protection, including, for example, certain aspects of our llama immunization and antibody affinity maturation approaches. However, trade secrets can be difficult to protect. Although we take steps to protect our proprietary information, including restricting access to our premises and our confidential information, as well as entering into agreements with our employees, consultants, advisors and potential collaborators, third parties may independently develop the same or similar proprietary information or may otherwise gain access to our proprietary information. As a result, we may be unable to meaningfully protect our trade secrets and proprietary information.
