2106.03, I: clarify Nuijten paragraph "tangible" explanation

Please see MPEP 2106.03, I. (Jan. 2018), at 18, right column. The second non-bulleted paragraph (“paragraph A”) begins: “Even when a product has a physical or tangible form, it may not fall within a statutory category” (at 2100-19). Since paragraph A solely relates to Nuijten,* I suggest revising paragraph A to expressly relate to signals, and to clarify the meaning of “tangible.” For example, I propose revising paragraph A, up to the first citation, as follows ([[deletions]], __insertions__):


__A transitory, propagating signal is real and can be measured. However, it does not have a__ [[Even when a product has a]] physical or tangible __(i.e., material)__ form, [[it may not]] __and therefore does not__ fall within a statutory category. For instance, a transitory signal [[, while physical and real,]] does not possess concrete structure that would qualify as a device or part under the definition of a machine, is not a tangible __(i.e., material)__ article or commodity under the definition of a manufacture (even though it is man-made and physical in that it exists in the real world and has [[tangible]] __perceptible__ causes and effects), and is not composed of matter such that it would qualify as a composition of matter. * * *


Merriam-Webster gives two senses for “tangible”: palpable and material. The Nuijten decision uses both senses of the word. The Nuijten court stated that a “transient electric … transmission … exists in the real world and has tangible causes and effects.” 500 F3d 1346, 1356. However, the court found the “claimed signals” were non-statutory, because “any tangibility arguably attributed to a signal is embodied in the principle that it is perceptible … signals within the scope of the claim do not themselves comprise some tangible article or commodity.” Id. Nuijten therefore distinguishes “tangible … effects” (palpability) from a “tangible article” (materiality). Id. A “signal” is palpable, but is not material, so is non-statutory.


Paragraph A does not reflect this distinction. Paragraph A states that a “product” with a “tangible form … may not fall within a statutory category.” MPEP, supra. However, Nuijten found that the signals at issue did not have a “tangible form.” Nuijten at 1356. Therefore, the first sentence of paragraph A does not conform to the cited holding and should be amended. Thanks for considering this request!


* Paragraph A also cites Mentor Graphics, which simply applies the holding of Nuijten.
