Marquardt GmbH has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to ”competition” would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Exhibit Conf. TypeRational Exh 04 - Block DiagramPermanentIncludes proprietary internal oscillator information. Exh 05 - SchematicsPermanentIncludes proprietary design information Exh 10 - BOM + PlacementPermanentIncludes proprietary design information Long Term Confidentiality (Permanent):Marquardt GmbH requests that any exhibits listed above as permanently confidential be permanently withheld from public review. Wherein Long Term Confidentiality is not an option for specific exhibits with ISED, this request applies only to the FCC application for those exhibits. Short-Term Confidentiality (FCC Only):Marquardt GmbH requests that any exhibits selected above as short term confidential be withheld from public view for a period of days (noted above) from the date of the Grant of Equipment Authorization and prior to marketing.
