Superconductor Technologies Inc. Announces Issuance of U.S. Patent 8,290,553

 Patent covers RCE-CDR deposition equipment used to develop STI's production
                         scale Conductus® 2G HTS wire

     STI extends technology leadership to support global market position

AUSTIN, Texas, Dec. 4, 2012 (GLOBE NEWSWIRE) -- Superconductor Technologies
Inc. (Nasdaq:SCON) ("STI"), a world leader in the development and production
of high temperature superconducting (HTS) materials and associated
technologies, announced the U.S. Patent and Trademark Office (USPTO) has
issued a critical patent on STI's Reactive Co-Evaporation Cyclic Deposition
and Reaction (RCE-CDR) device and method for fabricating HTS thin films for 2G
HTS wire. The newly issued patent, U.S. Patent No. 8,290,553, is entitled
"Device and Method for Fabricating Thin Films by Reactive Evaporation" and
expires in 2025.

"This patent issuance represents another step forward in the execution of our
intellectual property (IP) strategy in conjunction with our Conductus® 2G HTS
wire development," said Jeff Quiram, STI's President and CEO. "As part of our
strategy to capture market potential, we are utilizing existing IP as the
foundation for the commercial development of Conductus 2G HTS wire. We will
continue to focus on strengthening our global IP portfolio to support our
growing market position."

In addition, the European Patent Office recently indicated that it is prepared
to grant a patent on STI's optimized composition of yttrium barium copper
oxide (YBCO), expanding the US Patent 7,867,950 issued January 11, 2011.

AboutSTI's 2G HTS Wire RCE-CDR Manufacturing

Conductus® unique RCE-CDR HTS deposition offers several key advantages to
successfully commercialize HTS wire for large, emerging markets. Importantly,
HTS deposition using RCE-CDR requires fewer manufacturing steps than alternate
deposition methods like MOD, MOCVD and PLD. Fewer steps reduce total
processing time and increase the likelihood of higher yield. Conductus®
highly controlled RCE-CDR deposition process grows crystalline structures from
very low cost raw materials in their bulk, solid state. Other YBCO growth
approaches are not as controlled and usually require the use of costly
chemical mixtures to deposit HTS materials. The competing processes require
more buffer layers for proper crystal growth which increases complexity and
runtimes and reduces yield. Conductus® growth process is simple, repeatable
and commercially proven. In addition to the lower direct cost of raw
materials and the use of inexpensive substrate material, Conductus®
manufacturing process will be designed for high throughput and a large HTS
growth area. Fewer process steps allows for less production equipment per km
of wire, which in turn translates into lower cap-ex, less electricity use and
a smaller production footprint.
