在美、欧、日,缬沙坦的市场是由诺华公司旗下的代文品牌所占领的;在巴基斯坦,市
场由本土的Efroze化工旗下的Angiotan品牌所占有;在印度,市场被印度西普拉公司的
Valzaar品牌所占据;诺华公司的另一品牌Tareg拥有着埃及市场。在中国市场中,诺华
公司的代文占有大多数市场,而国产缬沙坦品牌以价格优势也占有了部分市场,常见品
牌包括有怡方、霡欣、丽珠维可、缬克、佳菲、穗悦、托平等。

c****d 发帖数: 681 | 8 多谢。使劲google/百度了一番,自问自答一下,代文那个分子在中国重来没有申请过
专利和行政保护,也不符合申请行政保护的要求,所以中国企业可以合法生产
第三世界国家很多都在做了。

b******e 发帖数: 3348 | 9 小分子的药好仿,大分子的药就算没Pattern也不一定仿得出来 |
p*******8 发帖数: 158 | 10 以前在国内我就做个这样类似的药,号称新药,不过是国内不行政保护的瑞士专利药。
好处是复制成本低,利润高; 当然竞争对手也多啊,看谁先申报成功。 剂型技术落后
,只能搞针剂。 国内99.9%都是这种短平快模式,要不生产污染大的原料药, 要不搞
些西式中药。 |

p*******8 发帖数: 158 | 14 自己做有点悬,毕竟就算仿制药,也还要完成N多药监局要求的材料。首先,这种仿制
药一般没有大规模现成的原料药可以买到,需要有机合成组的开发简单的合成路线,小
试,中试,等等, 这一步就还是很费劲的。然后是formulation, 针剂简单些,药膏凝
胶之类麻烦些。 后面质量控制, 动物实验。 一般是做分析的人领导一个project,从
头到尾都得追踪 和别的组协调,编写申报documents。 即使申报成功,生产起来问题
更多。 当然如果能承包一个药厂,还是可以做的。 不过药监局的关系, 市场推销,
都是更重要的。

Diovan compound patent is US 5,399,578, it doesn't have a corresponding
Chinese patent, which means this compound is not protected in China (
although it's protected in HongKong by HK219996). This can be easily found
out if you know how to use EPO worldwide patent database. Do the number
search and check the worldwide patent in the same patent family.
China was not a viable market for big pharmas 20 years ago so it's quite
common for some old products, the innovators didn't apply for patent
protections in China.
But nowadays, China is becoming an important market on every big pharma's
marketing map. Things like Diovan will become rare, more and more unlikely.

L******r 发帖数: 522 | 18 There are several general concepts might be helpful to understand the
situation:
1. A lot of later filed patent applications try to include very broad claims
which would cover prior art disclosed/claimed information. Even such
claims are included in the later filed applications, unlikely these claims
will be supported and granted by patent office during examination. Patent
application is not equal to patent.
2. To file a PCT (WO applications) doesn't mean the innovation will
automatically be protected worldwide. PCT doesn't provide any real
protection. It just establishes the worldwide priority. The patentee has
to enter so-called "national phase" in certain time and prosecute in each
individual territory to secure granted patent to be able to obtain patent
protection in that territory. If the PCT didn't enter certain "national
phase" timely and be granted as patent, the innovation won't be protected in
that territory.
3. If there is a foreign priority (for example, somebody first filed in
China by a CN XXXXX), the PCT has to be filed in 12 months after the filing
date of the foreign priority otherwise the foreign priority will become
prior art and the innovation is not eligible to be filed as a PCT for
worldwide protection.
Base on above patent 101, you can see WO 97/30036 won't give Diovan (
Valsartan) any protection because:
1. Diovan foreign priority was filed in 1991. Nobody can file PCT to claim
it worldwide 5-6 years later.
2. WO 97/30036 didn't enter any national phase other than Australia.
