June 6, 2020 Federal Communications Commission 7435 Oakland Mills Road Columbia MD 21046 Subject: Request for Long Term Confidentiality of Certain Protected Documents FCC ID: 2AMDTWCDB To Whom It May Concern: Pursuant to the provisions of 47 CFR § 0.457 and § 0.459 and KDB 726920, Humanscale Corporation (“Humanscale”) requests that the Federal Communications Commission treat the following attachments as confidential and trade secret documents and thus indefinitely withhold them from public inspection or public disclosure. Exhibit Type Attachment__________ Schematic Diagram Item 8 – Schematic,* Operational Description Item 9 – Operational Description,* Block Diagram Item 10 – Block Diagram,* Antenna Specification Item 12 – Antenna Spec,* *followed by Nova Series Model N with Wireless Charging Desktop Base – external 20200526 The documents noted above contain detailed system and equipment descriptions that Humanscale uses in its business on a confidential basis subject to non-disclosure agreements. Humanscale considers these documents to be confidential and proprietary trade secret information regarding the design and/or operation of the equipment. These documents represent a custom electrical and hardware design which otherwise would not be made available or released to the general public. These documents provide Humanscale with an economic advantage over its competitors who market and sell competing products. The unauthorized or public disclosure of these documents at any time while FCC ID 2AMDTWCDB is on the market would have an adverse economic impact to Humanscale’s business. Apart from the documents noted above, Humanscale expects that all photos, measurement test reports, FCC ID label format(s), and correspondence between Humanscale, our authorized agent and the Commission during the certification review process will automatically remain confidential up until the equipment authorization for FCC ID 2AMDTWCDB is granted.
