Innovate is a special compendium of articles written by and for AIPLA members. Designed as an online publication, INNOVATE features magazine-like articles of 500-1,500 words in length on a wide variety of topics in IP law today.
Any current AIPLA member in good standing may submit an article for inclusion in INNOVATE throughout the year. IP law students, in particular, are strongly encouraged to submit articles for publication.
An ad-hoc sub-committee comprised of volunteers from AIPLA's Special Committee on Publications, the Fellows Committee, and others will review and edit submitted articles prior to publication. View our submission guidelines.

The market for 3D printing continues to grow and analysts forecast that its overall economic impact will reach upwards of $100 billion by 2025.1 As 3D printing becomes more commonplace, some have begun to question whether it is any more environmentally friendly than the conventional manufacturing processes it seeks to replace.
Broadly described, 3D printing is any form of additive manufacturing that builds a 3D object by extruding material onto a platform in progressive layers. 3D printers and printing technologies have been around for about 30 years, but only recently has their adoption become widespread.
A variety of factors have contributed to the rise of 3D printing
Many of the technologies described in expired 3D printing patents were developed 20 or more years ago. As a consequence, they may not address modern day manufacturing challenges. New 3D printing technologies developed to address such challenges may not be described or even contemplated by these old patents. Opportunities
One area that appears fertile for pursuing patent protection are technologies for reducing the environmental impact footprint of 3D printing. In some respects, 3D printing is already eco-friendly. 3D printing facilitates the production of components with less material without sacrificing strength, for example. Other aspects of 3D printing, however, are considered problematic from an environmental perspective.4 Experts have warned that 3D printing may consume more energy than conventional production techniques in certain cases.5 Also, many 3D printing processes produce plastic by-products which are not reusable and/or emit fumes, some of which may be toxic.6 If 3D printing is to overtake the tooling market,
This challenge presents an opportunity for innovators in that they can potentially leverage the patent system to secure exclusive protection for their inventive solutions. When confronted with a technical problem, companies will sometimes commission a patent landscape study to gather information on how others have attempted to address the problem in the past, if at all. Most U.S. and foreign patent applications publish 18 months after filing and therefore can provide valuable insights on new products under development by competitors and which otherwise might not be publicly known. Additionally, due to the written description and enablement requirements, patents and pending applications can provide a wealth of technical know-how relevant to a particular technology. Understanding what others have done in the past can spark ideas on how to improve or tweak existing products and methods, as well as provide guideposts to the “white space” where there may be opportunities to obtain exclusivity.
How To Protect 3D Printing Innovations With A U.S. Utility Patent
A U.S. utility patent is “a grant to the patentee…of the right to exclude others from making, using, offering for sale, or selling throughout the United States, or importing the invention into the United States.” 7 This right to exclude is for a period of twenty years from the date the application for
To obtain a U.S. utility patent, each patent claim9 in a U.S. utility application must include
In addition, each patent claim must also be useful, novel, and not obvious. For example, a third party patent disclosing the same improved 3D printing material or tool and invented before the proposed invention may prevent the claim from being novel.11 Also, the differences between the claimed invention and one or more prior art patents, for example, must not be obvious to a person having ordinary skill in the art to which the claimed invention pertains.12
One claiming strategy may include having claims in a single utility patent application directed to at least one of an improved 3D printing process, a 3D printing system, software used to direct the 3D printer, and the 3D printed object, as relevant. In some circumstances, it may be helpful to conduct a patentability search to understand any third party patents and publications related to the proposed invention before filing. The patentability search results may help both the inventor understand the potential scope of the patent protection available before proceeding and the patent drafter craft a claim strategy tailored to the same.
The subject matter of just some of the more recently issued utility patents relating to 3D printing improvements include support platens, printhead modules, brace structures, and deposition nozzles for additive manufacturing, for example.13 Various other patents relating to 3D printing include methods of producing orthopedic implants,
As a result, there appear to be opportunities for patent protection for both technologies reducing the environmental impact of 3D printing and 3D printing related technologies in many other sectors as well.15 Likewise, even if manufacturers do not consider obtaining utility patent protection for their 3D printing innovations, it may be prudent to search and review unexpired patents relating to their innovations to reduce any risks of infringing such patents before proceeding.

9. The claims of a patent define the scope of protection conferred by the patent. In other words, the claims define the limits of what is and what is not covered by the patent. A patent owner generally has the right to exclude others from making, offering to sell, selling, using, or importing into the U.S. things which fall within the scope of the claims.
