4-Antibody has obtained patent protection for its novel, proprietary technology platform allowing the development and optimization of fully human antibody drugs. The European patent for 4-Antibody’s core technology had already been granted October 13, 2004, and in the meantime, the nine month period for filing objections to issued patent EP 132 1477 B1 has expired. No objections against 4-Antibody’s patent have been filed to the EPA authorities, paving the way to entering the issued EP patent into national validation phases at key pharmaceutical markets. Since its inception, 4-Antibody Ltd. has broadened its intellectual property portfolio by filing 25 patent applications with the aim to protect the company’s core technology in major pharmaceutical markets globally.

Ulf Grawunder, CEO of 4-Antibody, comments, “The granting of the European patent for our core technology platform was one important and crucial milestone in the early development of our start-up company. While the European patent for our unique technology is important for securing its application in a very competitive industry environment, the patent will also be an important value driver for our company, because it is the basis for future, revenue-generating license agreements. We were particularly pleased that the EPA (European patent agency) endorsed all of the central claims in our patent application. Management will continue to strengthen 4-Antibody’s intellectual property portfolio in order to establish 4-Antibody as a global player in the field of therapeutic antibody drug development.”

The private placement has been offered exclusively to individuals who had helped the company in its early stages of creation.

Ulf Grawunder, CEO of 4-Antibody, comments, “We are very pleased about the development of the company since its inception and venture capital seed financing. The founders and first-round investors accepted the wish of selected private individuals, who have been extremely supportive in the creation and the early development of our start-up company, to invest into our company before completion of further financing activities.”

Wulf Haasner, Director of Finance and Operations adds, “These private individuals know the company very well and management welcomes the endorsement of its activities by these distinguished individuals and industry experts. 4-Antibody will continue to increase value for the new and existing shareholders.”
