Patent number: 11975076Abstract: The present invention relates to antibody-drug conjugates (ADCs) wherein a plurality of active agents are conjugated to an antibody through at least one branched linker. The branched linker may comprise a branching unit, and two active agents are coupled to the branching unit through a secondary linker and the branching unit is coupled to the antibody by a primary linker. The active agents may be the same or different. In certain such embodiments, two or more such branched linkers are conjugated to the antibody, e.g., 2-4 branched linkers, which may each be coupled to a different C-terminal cysteine of a heavy or light chain of the antibody. The branched linker may comprise one active agent coupled to the branching unit by a first branch and a second branch that comprises a polyethylene glycol moiety coupled to the branching unit. In certain such embodiments, two or more such branched linkers are conjugated to the antibody, e.g.Type: GrantFiled: November 12, 2021Date of Patent: May 7, 2024Assignee: LegoChem Biosciences, Inc.Inventors: Yong Zu Kim, Yeong Soo Oh, Jeiwook Chae, Ho Young Song, Chul-Woong Chung, Yun Hee Park, Hyo Jung Choi, Kyung Eun Park, Hyoungrae Kim, Jinyeong Kim, Ji Young Min, Sung Min Kim, Byung Soo Lee, Dong Hyun Woo, Ji Eun Jung, Su In Lee

Patent number: 11979504Abstract: Incidents involving confidentiality and vigilance against user privacy invasions raise doubts as to current third-party data collection procedures. Personally identifiable information (PII) is being abused for medical data breaches, identity theft, spam, phishing, cyber spying, etc. A great amount of data is flowing from users to companies for prediction and analysis of data-centric markets. It is thus difficult to track PII flow and genuineness. Blockchain technology, which is an “immutable” distributed ledger, can efficiently track PII exchange, storing, and distribution. In contrast, the EU general data protection regulation (GDPR) in progress claims “a right to forget” and a right “to delete”. However, the present specification proposes an off-chain blockchain architecture using both a local database and a distributed ledger to guarantee a trustable PII life cycle.Type: GrantFiled: December 31, 2018Date of Patent: May 7, 2024Assignee: INJE UNIVERSITY INDUSTRY-COOPERATION FOUNDATIONInventors: Jin Hong Yang, Chul Soo Kim, Md Mehedi Hassan Onik, Nam Yong Lee

Patent number: 11761892Abstract: Building blocks are provided for on-chip chemical sensors and other highly-compact photonic integrated circuits combining interband or quantum cascade lasers and detectors with passive waveguides and other components integrated on a III-V or silicon. A MWIR or LWIR laser source is evanescently coupled into a passive extended or resonant-cavity waveguide that provides evanescent coupling to a sample gas (or liquid) for spectroscopic chemical sensing. In the case of an ICL, the uppermost layer of this passive waveguide has a relatively high index of refraction that enables it to form the core of the waveguide, while the ambient air, consisting of the sample gas, functions as the top cladding layer. A fraction of the propagating light beam is absorbed by the sample gas if it contains a chemical species having a fingerprint absorption feature within the spectral linewidth of the laser emission.Type: GrantFiled: August 20, 2021Date of Patent: September 19, 2023Assignee: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Jerry R.

DETUNED ANTINODE ENHANCEMENT FOR IMPROVED TEMPERATURE INDEPENDENCE IN INFRARED LIGHT EMITTING DIODES
Publication number: 20220375905Abstract: Improved temperature independence in infrared light emitting diodes (IRLEDs). The active stage groups (ASGs) occur at or at an integer multiple of each antinode of the e-field of the desired center wavelength. The structure is designed to yield increased efficiency at low (cryogenic) temperatures with a wide range of operational temperature independence. The structure may be designed to provide a wide range of temperature independent operation near room temperature. The spacing (S) between the centers of the active stage groups may be varied to create a more broad and shallow peak of the temperature dependence of the antinode enhancement. The IRLED may be an interband cascade LED.Type: ApplicationFiled: May 10, 2022Publication date: November 24, 2022Inventors: Joseph D LaVeigne, Thomas E Danielson, Igor Vurgaftman, Chadwick L Canedy, Mijin Kim, Chul Soo Kim, William W Bewley, Charles D Merritt, Jerry R Meyer -
