ALEXANDRIA, Va., Jan. 28 -- United States Patent no. 12,534,721, issued on Jan. 27, was assigned to Illumina Inc. (San Diego).

"Quantitative detection and analysis of moleculesip" was invented by Robert Meltzer (Belmont, Mass.).

According to the abstract* released by the U.S. Patent & Trademark Office: "The invention provides systems and methods for making sequencing libraries that are useful for quantitatively analyzing nucleic acids in a sample. Sample nucleic acids are randomly cleaved at, and PCR handled are attached to, a random cut site.
